Description:
DESCRIPTION BIPHENYL DERIVATIVE OR ITS SALT, AND PESTICIDE CONTAINING IT AS AN ACTIVE INGREDIENT TECHNICAL FIELD The present invention relates to a biphenyl derivative or its salt, and a pesticide containing it as an active ingredient.

BACKGROUND ART W098/37068 discloses N- (3, 3-dimethylbutyl)-3- (2- methoxyphenyl) benzamide and N- (3, 3-dimethylbutyl)-3- (2- fluorophenyl) benzamide in the table on p. 106. Further, W099/23073, W02003/99776 and W02004/039753 disclose compounds having a biphenyl structure. However, they are not compounds to be used for agricultural or horticultural bactericides and/or fungicides.

DISCLOSURE OF THE INVENTION Many conventional agricultural, horticultural and pharmaceutical bactericides or fungicides have their own characteristics in their controlling effects over pests which cause plant diseases. Some have a slightly poorer curative effect as compared with a preventive effect, and some have a residual effect which lasts only for a relatively short period of time, so that their controlling effects against pests tend to be practically

insufficient in some cases. Accordingly, it has been desired to develop a novel compound which has a strong controlling effect against pests which cause plant diseases.

The present inventors have conducted extensive studies to overcome the above problems and as a result, have found that use of the compound represented by the formula (I) as an active ingredient presents excellent controlling effects against various plant diseases, particularly powdery mildew of barley, wheat, vegetables, fruits and flowering plants, downy mildew of vegetables and fruits, and rice blast. Thus, the present invention has been accomplished.

Namely, the present invention provides a pesticide containing a biphenyl derivative represented by the formula (I) or its salt, as an active ingredient: wherein, X and Y are each independently a halogen atom; a hydroxyl group; a formyl group; an alkyl group which may be substituted by halogen, alkoxy or alkylthio; a nitro group; an amino group which may be substituted by alkyl ; an alkoxy group which may be substituted by halogen or alkoxy; an aryloxy group which may be substituted by halogen or haloalkyl ; a heterocyclic oxy group which may

which may be substituted by alkyl ; an alkylcarbonylamino group; a formyl group; or a cyano group, and m and n are each independently 0,1, 2,3 or 4.

Greene, P. G. M. Wuts, in"Protective Groups in Organic Synthesis" (3rd Edition, 1999). Such protective groups may suitably be selected for use depending upon the reaction conditions. In the method of employing such a protective group, after carrying out the reaction by using such a protective group, the protective group may be removed or converted to a desired group, as the case

requires, to obtain a desired compound. The reaction may be carried out by using a method known to those skilled in the art, such as usual esterification, amidation, dehydration, diazotization, oxidation, etc.

Preferred embodiments of the process for producing the compound of the formula (I) will now be described.

PROCESS 1 x fT ./" (Z) n kty >/, X Y) m X </ () \ R P"Transition (ici) metal (I) catalyst In the above reaction formulae, X, Y, Z, m, n, A, R1 and R2 are as defined above, L is a leaving group, and M is a metal.

As shown by the above flow, the compound of the formula (I) may be prepared by coupling a compound of the formula (II) with a compound of the formula (III) in the presence of a transition metal catalyst. The reaction may be carried out in accordance with a known method (e. g.

Comprehensive Organic Synthesis, Volume 3,481, 1991 or Synthetic Communications, Volume 11,513, 1981). The leaving group represented by L in the formula (II) may, for example, be halogen or trifluoromethane sulfonyloxy, and the metal represented by M in the formula (III) may, for example, be hydroxyboron, alkylboron, alkoxyboron, halogenated magnesium, halogenated zinc, alkyltin,

alkylsilicon, alkoxysilicon, halogenated silicon, alkylaluminum or halogenated aluminum. The transition metal catalyst to be used for the reaction, means a transition metal compound or a complex of a transition metal compound with an optional ligand. It may, for example, be palladium/carbon (Pd/C), tetrakis (triphenylphosphine) palladium (0), bis (dibenzylideneacetone) palladium (0), tetrakis (dibenzylideneacetone) palladium (0), palladium (II) acetate/triphenylphosphine, palladium (II) acetate/tricyclohexylphosphine, dichloropalladium (II)/1, 1'- bis (dicyclohexylphosphino) ferrocene, tetrakis (triphenylphosphine) nickel (0), bis (1,5- cyclooctadiene) nickel (0), nickel acetylacetonate (II), dichlorobis (triphenylphosphine) nickel (II) or tetrakis (triphenylphosphine) platinum (0). In the case of a metal catalyst, one preliminarily isolated may be employed, or a transition metal compound and a ligand are mixed in an optional solvent for reaction and may be used without isolation. The transition metal catalyst may be used in a ratio of from 0.001 to 0.2 equivalents, preferably from 0.01 to 0.1 equivalent, to the compound of the formula (II) Further, the reaction may be carried out in the absence or presence of a solvent not to hinder the reaction, for example, a ketone such as acetone, methyl ethyl ketone or cyclohexanone; an ether

such as diethyl ether, diisopropyl ether, tetrahydrofuran, 1,4-dioxane, dimethoxyethane or diethylene glycol dimethyl ether; an ester such as ethyl acetate or methyl acetate; an alcohol such as methanol, ethanol, n-propanol or isopropanol; an aromatic hydrocarbon such as benzene, chlorobenzene, nitrobenzene or toluene; a nitrile such as acetonitrile; N, N-dimethylformamide; N, N- dimethylacetamide; dimethylsulfoxide ; or water. In some cases, two or more such solvents may be used in combination as a mixed solvent.

At the time of the reaction, the compound of the formula (II) and the compound of the formula (III) may be used in equal equivalent amounts or, one may be used in excess of the other. Further, in some cases, it may be advantageous to carry out the reaction in the presence of a base to let the reaction proceed smoothly. Such a base may, for example, be an alkali metal carbonate such as sodium carbonate, potassium carbonate or cesium carbonate; an alkali metal hydrogencarbonate such as sodium hydrogencarbonate; an alkaline earth metal carbonate such as calcium carbonate; an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide; an alkaline earth metal hydroxide such as calcium hydroxide; an inorganic salt such as cesium fluoride or potassium fluoride, or triethylamine, pyridine or 4- (N, N-dimethyl amino) pyridine. The base is used usually in a ratio of from 1.0 to 20 equivalents,

preferably from 1.0 to 3.0 equivalents, to the compound of the formula (II).

The reaction temperature is usually from-70°C to 300°C, preferably from 0°C to the boiling point of the solvent to be used. The reaction time varies depending upon the reaction temperature, the quantity for reaction, the reaction pressure, etc. , but it is usually selected within a range of from 1 to 72 hours.

PROCESS 2 The compound of the formula (I-1) i. e. the formula (I) wherein A is a carbonyl group, may be prepared also by the following process.

In the reaction formulae, X, Y, Z, m, n, R and R2 are as defined above.

As shown by the above flow, the compound of the formula (I-1) may be prepared by an amidation reaction of a compound of the formula (VI) with a compound of the formula (VII).

The amidation reaction may be carried out by condensing the compound of the formula (VI) with the compound of the formula (VII) in the presence of a condensing agent. Such a condensing agent may, for example, be dicyclohexylcarbodiimide (DCC),

diisopropylcarbodiimide (DIPC), 1-ethyl-3- (3- dimethylaminopropyl) carbodiimide (WSC) or 1, 1'- carbonylbis-lH-imidazole (CDI). A solvent which may be used, may, for example, be an aromatic hydrocarbon such as benzene, toluene or xylene, an ether such as diethyl ether, tetrahydrofuran (THF), 1,4-dioxane or dimethoxyethane, a halogenated hydrocarbon such as dichloromethane, 1,2-dichloroethane or chloroform, N, N- dimethylformamide (DMF), N-methyl-2-pyrrolidone (NMP) or pyridine. Further, in some cases, two or more such solvents may be used in combination as a mixed solvent.

Further, the compound of the formula (I-1) may also be prepared by a method of using a reactive derivative of the compound of the formula (VI) instead of the compound of the formula (VI) in the above amidation reaction.

Such a reactive derivative of the compound of the formula (VI) may, for example, be an acid halide, an acid anhydride or an active ester. The reaction may, for example, be carried out in accordance with the method disclosed in e. g. "Jikken Kagaku Koza (4th Edition)" compiled by Japan Chemical Society, vol. 22, (1992) published by Maruzen.
