Method of manufacturing Organoxysilane compd.

PROBLEM TO BE SOLVED: To provide a method for producing an organoxysilane compound efficiently by improving catalyst activity and regioselectivity, when an addition reaction is generated between an unsaturated bond-containing compound and a hydrogen organoxysilane compound by using a platinum compound-containing catalyst. SOLUTION: In this method for producing an organoxysilane compound, an unsaturated bond-containing compound represented by general formula (1): CH2=CH-R1(1) (In the formula, R1is a 1-18C unsubstituted or substituted monovalent hydrocarbon group excluding a norbornenyl group, a monovalent heterocyclic ring-containing group, an organoxysilyl group or an organosiloxanyl group.) and a hydrogen organoxysilane compound represented by general formula (2): HSiR2n(OR3)3-n(2) (In the formula, R2is a 1-10C unsubstituted or substituted monovalent hydrocarbon group. R3is a 1-10C unsubstituted or substituted monovalent hydrocarbon group, and n is an integer of 0-2.) are hydrosilylated by using a platinum compound-containing catalyst in the presence of an ammonium salt of an inorganic acid. The objective organoxysilane compound can be produced efficiently at high reactivity and regioselectivity by this production method. COPYRIGHT: (C)2013,JPOandINPIT
