Cyanoethylation of Trichlorosilane. I. β-Addition.

Abstract

Abstract 1. Cyanoethylation of trichlorosilane was found to be catalysed by organic bases, benzoylperoxide, or platinized asbestos at about 160°C. The catalytic activities of organic bases increased in the order, dimethylaniline << quinoline < pyridine, piperidine < triethyl-amine. Pyridine hydrochloride and benzyltriethylammonium chloride has also catatytic effects. 2. The orientation of the addition reaction was found to be almost exclusively of the β-position. 3. An ionic mechanism was suggested for the organic base-catalysed addition reaction.
