BACKGROUND [0002] Alpha-olefins, especially those containing 6 to 20 carbon atoms, are important items of commerce. They are used as intermediates in the manu- facture of detergents, as monomers (especially in linear low-density polyethyl- ene), and as intermediates for many other types of products. As a consequence, improved methods of making these compounds are desired.

[0003] Most commercially produced C-olefins are made by the oligomeri- zation of ethylene, catalyzed by various types of compounds, see for instance B.

Cornils, et al. , Ed. , Applied Homogeneous Catalysis with Organometallic Com- pounds, A Comprehensive Handbook, Vol. 1, VCH Verlagsgesellschaft mbH, Weinheim, 1996, p. 245-258. The major types of commercially used catalysts are alkylaluminum compounds, certain nickel-phosphine complexes, and a titanium halide with a Lewis acid such as Aids. In all of these processes, significant amounts of branched and/or internal olefins and/or diolefins are produced. Since in most instances these are undesirable and often difficult to separate, these by- products are avoided commercially.

[0004] Recently, a series of cationic (a-diimine) nickel (II) catalysts for ethylene oligomerization and propylene dimerization were reported. (Organomet- allics 1999,18, 65-74; Organometallics 1997,16, 2005-2007; WO 00/10945; US 5,880, 323). These catalysts are highly active. But the corresponding pre-catalysts have low organic-solvent solubility. Therefore, their characterization and appli- cation is highly restricted. Catalyst solubility is desired for continuous solution reactors and for supporting the catalysts for use in a slurry phase reactor or fixed- bed reactor. Additionally, a soluble pre-catalyst is easier to completely activate to its catalytic form, and often provides a catalyst with significantly higher catalyst activity. In view of the difficulty and practical limitations in using insoluble or poorly soluble catalysts, soluble, a-olefin-producing catalyst systems need to be developed.

SUMMARY [0005] Invention catalyst systems comprise nickel or palladium compo- nents (pre-catalyst or catalyst precursor) and an activator (cocatalyst) ) that can produce a-olefins in a solution-or a slurry-phase oligomerization procedure. The soluble oligomerization catalyst precursors of this invention are represented by the general formula I. where M is nickel or palladium; Pn is a Group 15 atom, preferably nitrogen ; H is hydrogen; R7 and R8 are independently 'hydrogen or Cl-C30 hydrocarbyl radicals that may be joined to form an aromatic or non-aromatic cyclic ring structure ; R13, R14, R15, R16, R17, and R18 are independently 'hydrogen or C1-C30 hydrocarbyl radicals Optionally, one or more aromatic or non-aromatic structures may be formed by independently joining two or more adjacent # non-hydrogen R13, R14 or Rl5 ; or non-hydrogen Rl6, Rl7 or Rl8, R9, Rl°, R11 and R12 are independently hydrogen, # halogen, hydroxyl, alkoxy, or . Cl-C30 hydrocarbyl radicals provided that at least one R ?-12 radical is not hydrogen; and two or more R9-12 may form a saturated or unsaturated ring structure.

[0007] Some invention embodiments relate to compositions comprising: a metal selected from nickel or palladium; an ancillary ligand system connected to the metal where the ancillary ligand sys- tem comprises 1,4-diazabutadiene ; and substituents connected to the 2 and 3 positions of the diazabutadiene; phenyl rings connected to the 1 and 4 positions of the diazabutadiene; (i) a catecholate ligand.

[0008] In another embodiment, this invention relates to a composition comprising: (I) a metal selected from nickel or palladium connected to a ligand comprising 1,4-diazabutadiene : (a) having a phenyl ring connected to the 1 position of the di- azabutadiene, and (b) having a phenyl ring connected to the 4 position of the di- azabutadiene, and (c) where the 2 and 6 positions of both phenyl rings are con- nected to hydrogen radicals, and (d) where the 2 and 3 positions of the diazabutadiene are, each independently, connected to hydrogen or a hydrocarbyl group; and (II) a catecholate ligand connected to the metal.

[0009] In another embodiment, this invention relates to a composition comprising a catecholate ligand, palladium or nickel, and an ancillary ligand with the following structure: where Pn is a Group-15 element; H is hydrogen; R7 and R8 are independently hydrogen or Ci-go hydrocarbyl radicals, or both are Ci-C3o hydrocarbyl radicals that form a ring structure comprising one or more aromatic or non-aromatic rings; R13-Rl8 are, independently, hydrogen or C1-C30 hydrocarbyl radicals.

[0010] The compositions can be activated with cocatalyst activators, as are known in the art. Accordingly, invention embodiments also include such acti- vated compositions. These activated compositions react with ethylene to form ethylene oligomers.

[0011] Methods of producing these compositions are outlined in this document. Because of this, invention embodiments include methods of producing these compositions, as well.

DEFINITIONS [0012] The term"hydrocarbyl radical"is sometimes used interchangeably with"hydrocarbyl"throughout this document. For purposes of this disclosure, "hydrocarbyl radical"encompasses Cl-C5o radicals. These radicals can be linear, branched, or cyclic, and when cyclic, aromatic or non-aromatic. Thus, the term "hydrocarbyl radical", in addition to unsubstituted hydrocarbyl radicals, encom- passes substituted hydrocarbyl radicals, halocarbyl radicals, and substituted halo- carbyl radicals, as these terms are defined below.

[0013] Substituted hydrocarbyl radicals are radicals in which at least one hydrogen atom has been substituted with at least one functional group such as NR"2, OR", PR"2, SR", BR"2, SiR"3, GeR"3 and the like or where at least one non- hydrocarbon atom or group has been inserted within the hydrocarbyl radical, such as O, S, NR", PR", BR", SiR"2, GeR"2, and the like, where R"is independently a hydrocarbyl or halocarbyl radical.

[0014] Halocarbyl radicals are radicals in which one or more hydrocarbyl hydrogen atoms have been substituted with at least one halogen or halogen- containing group (e. g. F, Cl, Br, I).

[0015] Substituted halocarbyl radicals are radicals in which at least one hydrocarbyl hydrogen or halogen atom has been substituted with at least one functional group such as NR"2, OR", PR"2, SR", BR"2, SiR"3, GeR"3 and the like or where at least one non-carbon atom or group has been inserted within the halo- carbyl radical such as O, S, NR", PR", BR", SiR"2, GeR"2, and the like where R"is independently a hydrocarbyl or halocarbyl radical provided that at least one halo- gen atom remains on the original halocarbyl radical.

[0016] The hydrocarbyl radical can be independently selected from methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, non- <BR> <BR> <BR> <BR> adecyl, eicosyl, heneicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, nonacosyl, triacontyl, propenyl, butenyl, pentenyl, hexenyl, heptenyl, octenyl, nonenyl, decenyl, undecenyl, dodecenyl, tridecenyl, tetrade- cenyl, pentadecenyl, hexadecenyl, heptadecenyl, octadecenyl, nonadecenyl, eicosenyl, heneicosenyl, docosenyl, tricosenyl, tetracosenyl, pentacosenyl, hexa- cosenyl, heptacosenyl, octacosenyl, nonacosenyl, triacontenyl, propynyl, butynyl, pentynyl, hexynyl, heptynyl, octynyl, nonynyl, decynyl, undecynyl, dodecynyl, tridecynyl, tetradecynyl, pentadecynyl, hexadecynyl, heptadecynyl, octadecynyl, nonadecynyl, eicosynyl, heneicosynyl, docosynyl, tricosynyl, tetracosynyl, penta- cosynyl, hexacosynyl, heptacosynyl, octacosynyl, nonacosynyl, or triacontynyl isomers. The radical may then be subjected to the types of substitutions described above.

[0017] The nickel or palladium component can also be described as com- prising at least one ancillary ligand that stabilizes the oxidation state of the transi- tion metal. Ancillary ligands serve to enforce the geometry around the metal center. In this disclosure, ancillary ligands comprise 1,4-diazabutadiene to which substituents are connected at the 2 and 3 positions and phenyl rings are connected to the 1 and 4 positions of the diazabutadiene. For purposes of this disclosure, all recited"diazabutadiene"is intended to indicate 1, 4-diazabuta-1, 3-diene.

[0018] The substituents at the 2 and 3 positions are independently hydro- gen or a hydrocarbyl radical. In some embodiments, a substituent is independ- ently hydrogen or a Cl-C30 hydrocarbyl radical. In these or other embodiments, two of these substituents link to form a ring structure comprising one or more, aromatic or non-aromatic rings.

[0019] For purposes of this disclosure, "catecholate"or"catecholate li- gand"encompasses a ligand comprising a phenyl ring. Two oxygen atoms con- nect to the phenyl ring at the ring's 1 and 2 positions. The ligand connects to the metal center of the catalyst precursor through both of these oxygen atoms. This leaves four hydrogen atoms connected to the phenyl ring at its 3,4, 5 and 6 posi- tions. Zero, one, two, three, or four of these hydrogen atoms can be substituted with a C1-C30 hydrocarbyl radical. Also, adjacent catecholate hydrocarbyl radicals can join to transform the catecholate into a substituted or unsubstituted, fused- multi-ring system.

[0020] For purposes of this disclosure oligomers include about 2-75 mer units.

[0021] In some structures throughout this specification, the ligand-metal connection is drawn with an arrow indicating that the electrons for the bond origi- nally came from the ligand. At other times, a solid line showing the bond's cova- lent nature represents the liquid-metal connection. One of ordinary skill in the art recognizes that these depictions are interchangeable.

DETAILED DESCRIPTION [0022] Due to the presence of a catecholate ligand, the catalyst becomes more soluble in most organic solvents such as hexane, toluene, methylene chlo- ride, and the like.

[0023] Examples of specific invention catalyst precursors take the fol- lowing formula where some components are listed in Table 1. When alkyl, alkenyl and alkynyl radicals are disclosed in this application, the term includes all isomers and all substitution types, as described above, unless otherwise stated.

For example, butyl includes n-butyl, isobutyl, and tert-butyl; pentyl includes n- pentyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, 1-ethylpropyl, and neopen- tyl ; butenyl includes E and Z forms of 1-butenyl, 2-butenyl, 3-butenyl, 1-methyl- 1-propenyl, 1-methyl-2-propenyl, 2-methyl-l-propenyl and 2-methyl-2-propenyl.

To illustrate members of the transition metal component, select any combination of the species listed in Table 1. For example, choosing the components in the first row, yields [1, 4-bis (phenyl)-1, 4-diaza-1, 3-butadiene] nickel catecholate. Any combination of components may be selected. The column labeled Rl9 R2o shows some examples of substituents that can serve as Rl9 and Ro. Of course, selecting a particular substituent for Rl9 is independent of the selection for Ro. In other words, the invention allows R19=R20, but does not demand it. The same goes for R7, R, R9, R10, R11, and R, as well.

[0026] Rl9 and Wo can further independently be defined as the following substituent: where R21, R22, and R23 are independently hydrogen or hydrocarbyl radicals.

Rl, W2 and R23 can be selected from radicals comprising: methyl, ethyl, ethenyl, ethynyl and all isomers of propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, hep- tadecyl, octadecyl, nonadecyl, eicosyl, heneicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, nonacosyl, triacontyl, propenyl, butenyl, pentenyl, hexenyl, heptenyl, octenyl, nonenyl, decenyl, undecenyl, do- decenyl, tridecenyl, tetradecenyl, pentadecenyl, hexadecenyl, heptadecenyl, oc- tadecenyl, nonadecenyl, eicosenyl, heneicosenyl, docosenyl, tricosenyl, tetra- cosenyl, pentacosenyl, hexacosenyl, heptacosenyl, octacosenyl, nonacosenyl, triacontenyl, propynyl, butynyl, pentynyl, hexynyl, heptynyl, octynyl, nonynyl, decynyl, undecynyl, dodecynyl, tridecynyl, tetradecynyl, pentadecynyl, hexade- cynyl, heptadecynyl, octadecynyl, nonadecynyl, eicosynyl, heneicosynyl, doco- synyl, tricosynyl, tetracosynyl, pentacosynyl, hexacosynyl, heptacosynyl, octa- cosynyl, nonacosynyl, or triacontynyl. In some embodiments R21 and R22 or R and R23 join together to form a ring structure.

The catecholate ligand can take the following formula: where R24, Ras, R2s and R2 are independently, hydrogen, methyl, ethyl, ethenyl, ethynyl and all isomers of propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, hep- tadecyl, octadecyl, nonadecyl, eicosyl, heneicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, nonacosyl, triacontyl, propenyl, bu- tenyl, pentenyl, hexenyl, heptenyl, octenyl, nonenyl, decenyl, undecenyl, dode- cenyl, tridecenyl, tetradecenyl, pentadecenyl, hexadecenyl, heptadecenyl, octade- cenyl, nonadecenyl, eicosenyl, heneicosenyl, docosenyl, tricosenyl, tetracosenyl, pentacosenyl, hexacosenyl, heptacosenyl, octacosenyl, nonacosenyl, triacontenyl, propynyl, butynyl, pentynyl, hexynyl, heptynyl, octynyl, nonynyl, decynyl, unde- cynyl, dodecynyl, tridecynyl, tetradecynyl, pentadecynyl, hexadecynyl, heptade- cynyl, octadecynyl, nonadecynyl, eicosynyl, heneicosynyl, docosynyl, tricosynyl, tetracosynyl, pentacosynyl, hexacosynyl, heptacosynyl, octacosynyl, nonacosynyl, and triacontynyl, phenyl, benzyl, fluoro, chloro, bromo, iodo, methoxy, ethoxy, propoxy, butoxy, and phenoxy. Some embodiments select at least one or two R24, R25, R26 or R27 to be a hydrocarbyl substituent such as butyl. Adjacent R24-Ra can connect to form substituted or unsubstituted ring structures, as well.

[0027] Below are examples in which the catecholate has been transformed into a fused ring system.

[1,4-diphenyl-diazobuta-1, 3-diene] [naphthalene-1,2-bis (olate) ] nickel; [1,4-bis (4-pentadecylphenyl) -diazobuta-1,3-diene] [4-butyl-naphthalene-1,2-bis (olate) ] nickel [1, 4-bis (4-ethylphenyl)-diazobuta-1, 3-diene] [1-butyl-naphthalene-2, 3-bis (olate) ] nickel [0028] These complexes can be synthesized by methods well known in the literature. First, the ancillary ligand should be prepared. One way of making these ancillary ligands is by the acid-catalyzed addition of an aniline (for phenyl- substituted diazo ligands) to a substituted or unsubstituted 2,3-butanedione.

[0029] Next comes preparation of the metal complex. Its preparation method uses a metal carbonyl complex, a bidentate or tridentate chelating ligand, and a 1,2-benzoquinone complex to form the desired complex. The metal car- bonyl, the ancillary ligand, and a benzoquinone are mixed in a 1: 1: 1 molar ratio.

The benzoquinone serves as an oxidizing agent. After its reduction, the molecule becomes the catecholate ligand that coordinates to the now-ancillary-ligand- coordinated transition metal. The synthesis of similar complexes is well known to those of ordinary skill in the art. An example of this oxidation-reduction reaction is illustrated below: Formation of a nickel (II) complex: [0030] For purposes of this disclosure, the term activator is used inter- changeably with cocatalyst. The activator functions to remove an abstractable li- gand from the transition metal. After activation the transition metal is left with an empty coordination site at which incoming a-olefin can coordinate before it is in- corporated into the oligomer or polymer. Any reagent that can so function with- out destroying the commercial viability of the oligomerization or polymerization process is suitable for use as an activator or cocatalyst in this invention. Exem- plary cocatalysts are discussed below.

[0031] Common activators well known in the literature including alumox- anes, such as methylalumoxane, modified methylalumoxane, ethylalumoxane and the like; aluminum alkyls such as trimethyl aluminum, triethyl aluminum, triiso- propyl aluminum and the like; alkyl aluminum halides such as diethyl aluminum chloride and the like; and alkylaluminum alkoxides are useful in the practice of this invention.

[0032] The alumoxane component useful as an activator typically is an oligomeric aluminum compound represented by the general formula (R"-Al-O)", which is a cyclic compound, or R" (R"-Al-0) nAlR"2, which is a linear compound.

In the general alumoxane formula, R"is independently a C1-C20 alkyl radical, for example, methyl, ethyl, propyl, butyl, pentyl, isomers thereof, and the like, and "n"is an integer from 1-50. Most preferably, R"is methyl and"n"is at least 4.

Methylalumoxane and modified methylalumoxanes are most preferred. For fur- ther descriptions see, EP 279586, EP 561476, W094/10180 and US Pat. Nos.

4,665, 208,4, 908,463, 4,924, 018,4, 952,540, 4,968, 827,5, 041,584, 5,103, 031, 5,157, 137,5, 235,081, 5,248, 801,5, 329,032, 5,391, 793, and 5,416, 229.

[0033] The aluminum alkyl component useful as an activator is repre- sented by the general formula R"A1Z2 where R"is defined above, and each Z is independently R"or a different univalent anionic ligand such as halogen (Cl, Br, I), alkoxide (OR") and the like. Most preferred aluminum alkyls include trieth- ylaluminum, diethylaluminum chloride, triisobutylaluminum, tri-n-octylaluminum and the like.

[0034] When alumoxane or aluminum alkyl activators are used, the cata- lyst-precursor-to-activator molar ratio is from about 1: 1000 to 10: 1; alternatively, 1: 500 tol : 1 ; or 1: 300 to 1: 10.

[0035] Additionally, discrete ionic activators such as [Me2PhNH] [B (C6Fs) 4], [Bu3NH] [BF4], [NH4] [PF6], [NH4] [SbF6], [NH4] [AsF6], [NH4] [B (C6Hs) 4] or Lewis acidic activators such as B (C6Fs) 3 or B (C6H5) 3 can be used, Discrete ionic activators provide for an activated catalyst site and a rela- tively non-coordinating (or weakly coordinating) anion. Activators of this type are well known in the literature, see for instance W. Beck. , et al. , Chem. Rev., Vol. 88, p. 1405-1421 (1988); S. H. Strauss, Chem. Rev. , Vol. 93, p. 927-942 (1993); US Pat. Nos. 5,198, 401,5, 278, 119,5, 387,568, 5,763, 549,5, 807,939, 6, 262, 202, and W093/14132, W099/45042 WO01/30785 and WO01/42249.

[0036] When a discrete ionic activator is used, the catalyst-precursor-to- activator molar ratio is from: 1: 10 to 1.2 : 1; 1: 10 to 10: 1; 1: 10 to 2: 1; 1: 10 to 3: 1; 1 : 10 to 5 : 1 ; 1: 2 to 1. 2: 1; 1: 2 to 10 : 1; 1: 2 to 2 : 1; 1: 2 to 3 : 1; 1: 2 to 5 : 1; 1: 3 to 1. 2: 1; 1 : 3 to 10 : 1; 1: 3 to 2 : 1; 1: 3 to 3 : 1; 1: 3 to 5 : 1; 1: 5 to 1. 2: 1; 1: 5 to 10 : 1; 1: 5 to 2 : 1; 1 : 5 to 3 : 1; 1: 5 to 5 : 1.

[0037] The catalyst-precursor-to-alkylating-agent molar ratio is from: 1: 10 to 10 : 1 ; 1 : 10 to 2 : 1 ; 1 : 10 to 25 : 1; 1: 10 to 3 : 1 ; 1 : 10 to 5 : 1; 1: 2 to 10 : 1; 1: 2 to 2 : 1; 1: 2 to 25: 1; 1: 2 to 3: 1; 1: 2 to 5: 1; 1: 25 to 10: 1; 1: 25 to 2: 1; 1: 25 to 25: 1; 1: 25 to 3: 1; 1: 25 to 5 : 1; 1 : 3 to 10: 1; 1 : 3 to 2 : 1; 1 : 3 to 25 : 1; 1 : 3 to 3 : 1; 1 : 3 to 5 : 1; 1 : 5 to 10: 1; 1 : 5 to 2 : 1; 1 : 5 to 25 : 1; 1 : 5 to 3 : 1; 1 : 5 to 5 : 1.

[0038] The catalyst systems of this invention can additionally be prepared by combining in any order, the bidentate ligand: where N, H, R13 R, Rls R", R", R", R7 and R8 are as previously de- fined, with a Group-10 halide salt which may optionally be coordinated by solvent (for example NiX2 or NiX2MeOCH2CH20Me where X = Cl, Br or I), and a 1,2- catecholate salt in a solvent, such as toluene, with dissolved activator compound (for example methylalumoxane). Similarly, the catalyst system can be prepared by combining in any order, the bidentate ligand, a neutral metal (such as Ni (CO) 4, Ni (COD) 2, Ni metal, Pd metal, Pd (PPh3) 4, Pd (Pcy3) 2, Pd (t-Bu3P) 2), and an ortho- quinone in a solvent, such as toluene, with dissolved activator compound (for ex- ample methylalumoxane). In either example, all reactants may be added in any order, or even essentially simultaneously. But some embodiments add the acti- vator last.

[0039] The solubility of invention catalyst precursors allows for the ready preparation of supported catalysts. To prepare uniform supported catalysts, the catalyst precursor should significantly dissolve in the chosen solvent. The term "uniform supported catalyst"means that the catalyst precursor or the activated catalyst approach uniform distribution upon the support's accessible surface area, including the interior pore surfaces of porous supports.

[0040] Invention supported catalyst systems may be prepared by any method effective to support other coordination catalyst systems, effective meaning that the catalyst so prepared can be used for oligomerizing olefin in a heteroge- nous process. The catalyst precursor, activator, suitable solvent, and support may be added in any order or simultaneously. The activator, dissolved in an appropri- ate solvent such as toluene can be stirred with the support material for 1 minute to 10 hours. The total volume of the activation solution may be greater than the pore volume of the support, but some embodiments limit the total solution volume be- low that needed to form a gel or slurry (about 100-200% of the pore volume). The mixture is optionally heated from 30-200°C during this time. The catalyst can be added to this mixture as a solid, if a suitable solvent is employed in the previous step, or as a solution. Or alternatively, this mixture can be filtered, and the result- ing solid mixed with a catalyst precursor solution. Similarly, the mixture may be vacuum dried and mixed with a catalyst precursor solution. The resulting catalyst mixture is then stirred for 1 minute to 10 hours, and the catalyst is either filtered from the solution, and vacuum dried, or vacuum or evaporation alone removes the solvent.

[0041] The catalyst precursor and activator can be combined in solvent to form a solution. The support is then added to this solution and the mixture is stirred for 1 minute to 10 hours. The total volume of this solution may be greater than the pore volume of the support, but some embodiments limit the total solu- tion volume below that needed to form a gel or slurry (about 100-200% pore vol- ume). The residual solvent is then removed under vacuum, typically at ambient temperature and over 10-16 hours. But greater or lesser times are possible.

[0042] The catalyst precursor may also be supported in the absence of the activator, in which case the activator is added to the liquid phase of a slurry proc- ess. For example, a solution of catalyst precursor is mixed with a support material for a period of about 1 minute to 10 hours. The resulting pre-catalyst mixture is then filtered from the solution and dried under vacuum, or vacuum or evaporation alone removes the solvent. The total volume of the catalyst precursor solution may be greater than the pore volume of the support, but the total solution volume can be limited below that needed to form a gel or slurry (about 100-200% of the pore volume).

[0043] Additionally, two or more different catalyst precursors may be placed on the same support using any of the support methods disclosed above.

Likewise, two or more activators may be placed on the same support.

[0044] Suitable solid particle supports typically comprise polymeric or refractory oxide materials. Porous supports (such as for example, talc, inorganic oxides, inorganic chlorides (magnesium chloride) ) that have an average particle size greater than 10 um can be used. Inorganic oxide materials as the support material including Group-2, -3,-4,-5,-13, or-14 metal or metalloid oxides also can be used. Catalyst support materials include silica, alumina, silica-alumina, and their mixtures. Other inorganic oxides may serve either alone or in combina- tion with the silica, alumina, or silica-alumina. These are magnesia, titania, zirco- nia, and the like. Lewis acidic materials such as montmorillonite and similar clays may also serve as a support. In this case, the support can optionally double as the activator component. But additional activator may also be used.

[0045] As is well known in the art, the support material may be pretreated by any number of methods. For example, inorganic oxides may be calcined, chemically treated with dehydroxylating agents such as aluminum alkyls and the like, or both.

[0046] The carrier of invention catalysts can have a surface area of 10-700 m2/g, or pore volume of 0.1-4. 0 cc/g, and average particle size from 10-500 pm.

But greater or lesser values may also be used.

[0047] Invention catalysts may generally be deposited on the support at a loading level of 10-100 micromoles of catalyst precursor per gram of solid sup- port; alternately from 20-80 micromoles of catalyst precursor per gram of solid support; or from 40-60 micromoles of catalyst precursor per gram of support. But greater or lesser values may be used provided that the total amount of solid cata- lyst precursor does not exceed the support's pore volume.

[0048] Additionally, oxidizing agents may be added to the supported or unsupported catalyst as described in WO 01/68725.

Process [0049] In the invention oligomerization processes, the process temperature may be-100°C to 300°C,-20°C to 200°C, or 0°C to 150°C. Some embodiments select ethylene oligomerization pressures (gauge) from greater than 0 kPa up to 35 MPa or 500 kPa-15 MPa.

[0050] The preferred and primary feedstock for the oligomerization proc- ess is the a-olefin ethylene; however, other a-olefins including but not limited to propylene and 1-butene may also be used alone or in combination with ethylene.

[0051] Invention oligomerization processes may be run in the presence of various liquids, particularly aprotic organic liquids. The homogeneous catalyst system, ethylene, a-olefins, and product are soluble in these liquids. A supported (heterogeneous) catalyst system may also be used, but will form a slurry rather than a solution. Suitable liquids for both homo-and heterogeneous catalyst sys- tems, include alkanes, alkenes, cycloalkanes, selected halogenated hydrocarbons, aromatic hydrocarbons, and in some cases, hydrofluorocarbons. Useful solvents specifically include hexane, toluene, cyclohexane, and benzene.

[0052] Also, under the correct conditions, mixtures of a-olefins containing desirable numbers of carbon atoms are obtained. Factor K from the Schulz-Flory theory (see for instance B. Elvers, et al. , Ed. Ullmann's Encyclopedia of Indus- trial Chemistry, Vol. A13, VCH Verlagsgesellschaft mbH, Weinheim, 1989, p.

243-247 and 275-276) serves as a measure of these a-olefins'molecular weights.

From this theory, K = n (Cn+2 olefin) /n (Cn olefin) where n (Cn olefin) is the number of moles of olefin containing n carbon atoms, and n (Cn+2 olefin) is the number of moles of olefin containing n+2 carbon atoms, or in other words the next higher oligomer of olefin. From this can be deter- mine the weight (mass) fractions of the various olefins in the resulting product.

The ability to vary this factor provides the ability to obtain the desired olefins.

[0053] Invention-made a-olefins may be further polymerized with other olefins to form polyolefins, especially linear low-density polyethylenes, which are copolymers containing ethylene. They may also be homopolymerized. These polymers may be made by a number of known methods, such as Ziegler-Natta- type polymerization, metallocene catalyzed polymerization, and other methods, see for instance WO 96/23010, see for instance Angew. Chem. , Int. Ed. Engl., vol. 34, p. 1143-1170 (1995); European Patent Application, 416, 815 ; and U. S.

[0054] Invention-made a-olefins may be converted to alcohols by known processes, these alcohols being useful for a variety of applications such as inter- mediates for detergents or plasticizers. The a-olefins may be converted to alco- hols by a variety of processes, such as the oxo process followed by hydrogenation, or by a modified, single-step oxo process (the modified Shell process), see for in- stance B. Elvers, et al. , Ed., Ullmann's Encyclopedia of Chemical Technology, 5th Ed. , Vol. A18, VCH Verlagsgesellschaft mbH, Weinheim, 1991, p. 321-327.

EXAMPLES [0057] The following examples are presented to illustrate the discussion above. Although the examples may be directed toward certain embodiments of the present invention, they do not limit the invention in any specific way. In these examples, certain abbreviations are used to facilitate the description. These in- clude standard chemical abbreviations for the elements and certain commonly ac- cepted abbreviations, such as: Me = methyl, Et = ethyl, Bu = butyl, Ph = phenyl, MAO = methylalumoxane, DAB = diazabutadiene, DAB (Me) 2 = 2, 3- dimethyldiazabutadiene, COD = cyclooctadiene and cy = cyclohexyl.

[0058] All preparations were performed under an inert nitrogen atmos- phere, using standard Schlenk or glovebox techniques, unless mentioned other- wise. Dry solvents (toluene, diethyl ether, pentane, and methylene chloride) were purchased as anhydrous solvents and further purified by passing them down an alumina (Fluka) column. 99.9% Ethylene was purchased from the BOC group (Surrey, United Kingdom). Formic acid (96%), methanol, 4-butylaniline, 2,3- butanedione, sodium sulfate, and 3,5-di-t-butyl-o-benzoquinone were purchased from Aldrich Chemical Company. Nickel tetracarbonyl can be purchased from Strem Chemicals, Inc. Deuterated solvents were dried with CaH and vacuum dis- tilled prior to use. The compounds are illustrated below: 2, 3-dimethyl-1, 4-diphenyl-1, 4-diaza-1, 3-butadiene can be prepared from literature methods.

Compound 1 Preparation of [2, 3-dimethyl-1, 4-diphenyl-1, 4-diaza-1, 3- butadiene] nickel (II) 3, 5-di-tert-butyl-catecholate) (Compound 1). Nickel tetra- carbonyl (0.86 g, 5 mmol) was condensed into an evacuated and frozen ampoule (having reserved volume of approximately 1 liter) containing 2, 3-dimethyl-1, 4- diphenyl-1, 4-diaza-1, 3-butadiene (1.11 g, 5 mmol) and 3, 5-di-tert-butyl-o- benzoquinone (1.10 g, 5 mmol) in 100 ml of degassed toluene. The ampoule was slowly warmed at-30°C for one hour and at-800C for the next two hours. Re- sulting solution was maintained at-10°C overnight. Dark green crystals were fil- tered, washed with light petroleum, and dried under vacuum. Yield 1.826 g (65%).

Oligomerization Reactions [0059] Oligomerization reactions were run in a 300-mL HastelloyC Parr reactor equipped with a mechanical stirrer. Catalyst was added to the reactor as a solution in toluene (75 ml) under argon. Ethylene was added to the reactor at 100 psig and then vented to maintain an ethylene atmosphere. Methylalumoxane so- lution (Albemarle, 30 wt % in toluene) was then added to the reactor. Thus, the catalyst was activated in the monomer's presence. The ethylene pressure was brought to the desired value. The aim was to maintain the reactor temperature at room temperature; but in cases where the reaction exotherm was very large, higher reaction temperatures were reached. After the reaction had run for an hour, the reactor was cooled in an acetone/dry ice bath, vented, and quenched with methanol. A sample of the product solution was analyzed by GC/MS after adding nonane as an internal standard. In the case of supported transition metal com- pounds, silica loaded samples were prepared by adding a solution of the transition metal complex in methylene chloride to silica followed by drying of the silica un- der vacuum overnight. MAO (0.35 g of 30 wt% MAO; Al/M molar ratio = 240 for the non supported run) was added to the reactor solution prior to adding the supported transition metal compound. The results of the oligomerization reactions are tabulated in Table 2: Table 2: Oligomerization Examples Com-CZ Rxn Exotherm Final Rxn Activity (mol Ka % cc olefin pound (mmol) (psig) (°C) Temp (°C) CZ/mol Nihr) (total) b 0. 0075 820 36-100 60 261, 900 0. 54 74 1 0. 0075 100 34-84 44 95,200 0.49 60 c 0.0019 100 24-61 44 227,400 0. 71 59 aK is based on C14/CI2 molar ratio for all isomers. bThese numbers are subject to the interpretation of the GC/MS spectra and are calculated from averaging the weight % of alpha olefin from the Cg, Cio, and C12 peaks. cl wt% of compound 1 loaded on silica; 0. 09g of 30wt% MAO added to the reactor providing an Al/M molar ratio of 260.
