Copper formate supported on sepiolite as a reusable catalyst for the hydrosilylation of olefins†

Abstract

Sepiolite, an abundant and environmentally friendly natural mineral, has been widely used as a catalyst support. Copper formate supported on sepiolite was prepared. The Cu(HCOO)₂/sepiolite catalyst showed high catalytic activity and selectivity in the anti-Markovnikov hydrosilylation of various olefins under mild conditions. Notably, the Cu(HCOO)₂/sepiolite catalyst exhibited remarkable reusability, maintaining its catalytic performance over at least 16 times.
