selective catalyst for the alcoholysis of diarylsilanes. Treatment with ethylenic alcohols leads in one step to 1-oxa-2-silacycloalcane. The alcoholysis of asymmetric organosilicon compounds proceeds predominantly with retention of configuration at the silicon atom. A mechanism is proposed to explain the experimental results.
