Metal-free photocatalytic hydrosilylation of olefins in the presence of photoinitiators

Abstract

A convenient metal-free photocatalytic hydrosilylation of a variety of linear and cyclic alkenes has been investigated. It was found that the free radical type photoinitiator Irgacure 2959 had a better effect on the hydrosilylation reaction; using 3 mol% photoinitiator Irgacure 2959, higher conversion rates can be obtained in the hydrosilylation of both some internal and terminal olefins. A new green method for hydrosilylation processes is achieved.
