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

The direct hydrogermylation of alkenes under Lewisacidcatalysis is reported. The use of borane B(C6F5)3 as a catalyst allows for a mild, metal-free hydrogermylation of alkenes and concomitant reduction of ketones and aldehydes. Regardless of electronic biases, anti-Markovnikov hydrogermylation is observed in high yields. Moreover, the process is scalable and proceeds under mild conditions at room
