Highly-active, graphene-supported platinum catalyst for the solventless hydrosilylation of olefins

Abstract

Herein we report the development of the first graphene-supported platinum catalyst that has demonstrated exceptional catalytic activity and stability for hydrosilylation reactions of olefins (TOF 4.8 × 10⁶ h⁻¹, TON = 9.4 × 10⁶). The catalyst also exhibited functional group tolerance over a broad range of industrially relevant substrates with minimal metal leaching. In addition, the catalyst system was successfully translated into a packed bed platform for continuous hydrosilylation reactions.
