PROCESS FOR PREPARATION OF .beta.-CYANOALKYLSILANES USING RUTHENIUM CATALYST ABSTRACT The present invention provides a process for the preparation of hydrolyzable .beta.-cyanoalkylsilanes. More particularly, this invention relates to the catalytic addition of an organohydrosilane to .alpha. ,.beta.-unsaturated olefinic nitriles to form .beta.-cyanoalkylsilanes. The present process employs a catalyst comprising a ruthenium compound. The preferred catalyst for the present process is a ruthenium compound having at least one tertiary phosphine ligand. The process is conducted at a temperature within a range of 50°C. to 300°C.
