A simple method for the hydrosilylation of olefins by using air-stable cobalt catalysts is developed. The catalyst system is composed of simple, cheap, and readily available cobalt(II) salts and well-defined terpyridine derivatives as cocatalysts or ligands, and the hydrosilylation processes can be processed smoothly under mild conditions without either Grignard reagents or NaHBEt 3 as activator.

A convenient metal-free photocatalytic hydrosilylation of variety of linear and cyclic alkenes have been investigated. It was found that the free radical type photoinitiator Irgacure 2959 had a better effect...

Hydrosilylation employing metal-organic frameworks (MOFs) as the catalyst are promising because of their high catalytic reactivity and sustainability of heterogeneous catalyst. A highly simple and efficient method for the hydrosilylation of olefins catalyzed by an air-stable MOF-cobalt catalysts is developed. This approach is featured by 0.1% of Co-MOFs catalyst with excellent reactivity, recyclability, and good functional group tolerance. The Co-MOFs can catalyze hydrosilylation of styrene or its derivatives with Ph 2 SiH 2 in the presence of NaBHEt 3 . Moreover, the catalysts we developed show excellent stability, and the activity is not significantly reduced after repeating the cycle for five times.
