Method for manufacturing silicon compound having substituents bonded to silicon atoms via Si-C bonds

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 formula

• HSiRn(Z)3−n
• where 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
• (R2COO)4−mSiR1m,
• where m is an integer from 0 to 3, each R1 is independently selected from the group consisting of C1 to C6 hydrocarbon groups and C1 to C6 alkoxy groups;
• and each R2 is independently selected from the group consisting of a hydrogen atom and C1 to C20 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
• where R3 is selected from the group consisting of C1 to C10 halogenated hydrocarbon groups, C1 to C10 alkyl groups, C6 to C10 aryl groups, a fluorine atom, a chlorine atom, a group described by formula OR4, and a group described by formula OSiR8R9R10;
• where, R4 is a C1 to C6 alkyl group;
• R8, R9, and R10 are each independently selected from a group consisting of C1 to C10 hydrocarbon groups, C1 to C10 halogenated hydrocarbon groups, a halogen atom, and a hydrogen atom;
• and R5, R6, and R7 are each independently selected from a group consisting of C1 to C10 hydrocarbon groups, a group described by formula —OS(O2)R3, C1 to C10 halogenated hydrocarbon groups, a halogen atom, and a hydrogen atom;
• and
• (e) a platinum catalyst.
