Patent ID: 8507630

Claim:
An organic inorganic composite catalyst comprising an organic inorganic composite material and palladium, wherein the organic inorganic composite material comprises an organosilicon compound and an inorganic oxide material, wherein the organosilicon compound and the inorganic oxide material are bonded to each other through a plurality of groups containing reactive silicon of the organosilicon compound, wherein the organosilicon compound is represented by formula (1) wherein X represents chlorine, bromine, iodine, a siloxy group, a hydroxy group, an alkoxy group, an allyl group or an imidazolyl group; Y provides for support of the palladium and represents a monovalent organic group containing at least one of a hydroxyl group, an alkoxy group, an aryloxy group, an isocyanato group, a mercapto group, a phosphino group, an amino group, an imino group, a halogen and a heterocyclic ring; A represents a linear alkylene group having 2 or more carbon atoms; R represents a methyl group, an ethyl group, a butyl group or a phenyl group; Q represents a methyl group, an ethyl group, a butyl group or a phenyl group; k is an integer of 1; n is an integer of 1 or 2; m is an integer of 2 or 3; l is an integer of 0 or 1; and l+m+n is 4; and wherein the organic inorganic composite material has palladium or a compound containing palladium supported thereon.
