Rhodium-catalyzed anti-Markovnikov hydrosilylation of alkenes

Rh-catalyzed anti-Markovnikov hydrosilylation of terminal alkenes and tertiary silanes using readily-available PPh3 as the ligand was reported. This method facilitated the effective synthesis of alkylsilanes with a wide substrate scope and high yields. Remarkably, both an unprecedented catalytic efficiency (TON up to 10,000) and excellent selectivity for the reaction of styrene and diethoxymethylsilane were achieved.
