Abstract

Abstract Allyl silane compounds represented by the formula (CH 2 ═CH--CH 2 --)R n SiCl 3-n (R represents, independently of each other, hydrocarbon groups with a carbon number of C 1 to C 8 ; n represents an integer from 0 to 3) are reacted with AX (AX stands for mercaptans, thiocarboxylic acids, carbon tetrachloride, or chloroform, the letter X represents, respectively, H bonded to sulfur in the case of mercaptans and thiocarboxylic acids, chlorine in the case of carbon tetrachloride, and H in the case of chloroform, and the letter A represents a residual group bonded to X) in the presence of radical generating agents, thereby obtaining allylsilane compounds represented by the formula (ACH 2 CHXCH 2 )R n SiCl 3-n (R, n, A and X have the same meaning as above).
