Abstract:
A method for manufacturing a silicon compound having substituents bonded to silicon atoms via Si-C bonds comprising reacting (a) an unsaturated compound selected from the group consisting of aromatic vinyl compounds and allyl halides with (b) a silicon compound having hydrosilyl groups described by formulaHSiR.sub.n (Z).sub.3-nwhere n is 0, 1, or 2, R is a hydrocarbon group, and Z is selected from the group consisting of silamino group, siloxy group, and siloxanoxy group; in the presence of (c) a carboxylic acid compound selected from the group consisting of(1) carboxylic acids(2) carboxylic anhydrides(3) silyl ester compounds of carboxylic acids described by formula(R.sup.2 COO).sub.4-m SiR.sup.1.sub.m,where m is an integer from 0 to 3, each R.sup.1 is independently selected from the group consisting of C.sub.1 to C.sub.6 hydrocarbon groups and C.sub.1 to C.sub.6 alkoxy groups; and each R.sup.2 is independently selected from the group consisting of a hydrogen atom and C.sub.1 to C.sub.20 saturated or unsaturated hydrocarbon groups which may including at least one atom selected from among oxygen, halogens, sulfur, and silicon;(d) a silyl ester of a sulfonic acid described by formula ##STR2##where R.sup.3 is selected from the group consisting of C.sub.1 to C.sub.10 halogenated hydrocarbon groups, C.sub.1 to C.sub.10 alkyl groups, C.sub.6 to C.sub.10 aryl groups, a fluorine atom, a chlorine atom, a group described by formula OR.sup.4, and a group described by formula OSiR.sup.8 R.sup.9 R.sup.10 ; where, R.sup.4 is a C.sub.1 to C.sub.6 alkyl group; R.sup.8, R.sup.9, and R.sup.10 are each independently selected from a group consisting of C.sub.1 to C.sub.10 hydrocarbon groups, C.sub.1 to C.sub.10 halogenated hydrocarbon groups, a halogen atom, and a hydrogen atom; and R.sup.5, R.sup.6, and R.sup.7 are each independently selected from a group consisting of C.sub.1 to C.sub.10 hydrocarbon groups, a group described by formula --OS(O.sub.2)R.sup.3, C.sub.1 to C.sub.10 halogenated hydrocarbon groups, a halogen atom, and a hydrogen atom; and(e) a platinum catalyst.
