Formation of disilanes in the reaction of stable silylenes with halocarbons

J Am Chem Soc. 2005 Oct 26;127(42):14730-8. doi: 10.1021/ja052584g.

Abstract

Reactions of stable silylenes 1 and 2 with a variety of halogenated organic compounds have been studied. Depending on the nature of the halocarbon, the products can be disilanes, LSiX-LSiR, or monosilanes, LSiXR, or a mixture of both types of products. Hexachloroethane reacts with the silylenes to give mainly the dichlorodisilane, LSiX-LSiX. The experimental results are rationalized in terms of several related free-radical chain mechanisms.
