Document Type and Number:
Japanese Patent JP3846507
Kind Code:
B2
Abstract:
A titanium catalyst for reaction between a carbon-carbon unsaturated bond and a compound having an electrophilic functional group or an electrophilic reagent, said titanium catalyst being composed of a titanium compound represented by the formula (1) below TiX<1>X<2>X<3>X<4> (where X<1>, X<2>, X<3>, and X<4> denote independently a halogen atom, C1-20 alkoxyl group, aralkyloxy group, aryloxy group, or -NRxRy group (where Rx and Ry denote independently a C1-20 alkyl group or aralkyl group), and any two of X<1>, X<2>, X<3>, and X<4> may form a ring.) and a Grignard reagent represented by the formula (2) below in a molar amount 1.5-2.5 times as much as the titanium compound. R<1>MgX<5> (where R<1> denotes a C2-10 alkyl group having a hydrogen atom at the beta position and X<5> denotes a halogen atom.) The titanium catalyst of the present invention activates the carbon-carbon unsaturated bond, which has a comparatively low reactivity, thereby catalyzing the reaction with an electrophilic functional group. It is inexpensive and industrially advantageous. When applied to reaction between a carbon-carbon unsaturated bond and an electrophilic functional group, it yields industrially a variety of adducts of a compound having a carbon-carbon unsaturated bond and a compound having an electrophilic functional group, and it also yields a variety of intramolecular adducts of a compound having a carbon-carbon unsaturated bond and an electrophilic functional group in the same molecule.
