The electrochemical reduction of aliphatic α, ω-dibromides in the presence of polychlorosilanes of the formula RnSiCl4− n (n= 0, 2) was shown to afford heterocyclic silicon compounds in good yield (up to 91%). In contrast to non-electrochemical methods of synthesis of silacycloalkanes, based on the ring closure of terminal unsaturated compounds, the electrochemical route does not produce α-methylated byproducts and the heterocycle ...
