Catalytic Hydrosilylation of Alkenes Mediated by Cobalt and Iron Disilyl Complexes

Abstract

Hydrosilylation of alkenes is an important transformation reaction in the production of a series of functional silicone materials. In the conventional system, platinum compounds have been widely used as catalyst for the hydrosilylation of alkenes. However, development of alternative catalysts that do not rely on the use of platinum is highly desired. In this work, we focused on the introduction of the chelating organosilyl ligands on the cobalt and iron centers to construct new catalysts, and it was found that cobalt disilyl complex can act as the highly active as well as selective catalyst for the hydrosilylation of various alkenes.
