摘要
A new method for producing a thioester group-containing organosilicon compound by a convenient reaction with dramatically improved workability generating reduced byproduct is provided. The method comprises reacting an organosilicon compound having a hydrolyzable silyl group and mercapto group with a carboxylic anhydride. Also provided are an organosilicon compound having a hydrolyzable silyl group, a thioester group, and carboxyl group in the same molecule capable of remarkably reducing hysteresis loss of the cured rubber composition; a compounding agent for rubber containing such organosilicon compound; a rubber composition prepared by blending such compounding agent for rubber; and a tire produced by using the cured rubber composition are also provided.
