The metathesis reactions of chlorovinylsilanes with copper(I) oxide are reported. The process is catalyzed by HCl which can be in situ generated via hydrolysis of chlorosilanes by traces of water present in the system. An appearance of olefin/CuCl π‐intermediates can provide a stereoselectivity of the process and alter the pathway of siloxanes formation employing Cu 2 O as the source of oxygen. It was also shown that acetonitrile may be available as a solvent for construction of the systems with large preparative capabilities, including those based on the use atmospheric oxygen in siloxane synthesis.
