Alkene hydrosilylation is typically performed with Pt catalysts, but inexpensive base-metal catalysts would be preferred. Here, we report a simple method for the use of air-stable cobalt catalysts for anti-Markovnikov alkene hydrosilylation that can be used under aerobic conditions without dry solvents or additives. These catalysts can be generated from low-cost commercially available materials. In addition, these catalysts possess good catalytic ability for both hydrosilanes and hydroalkoxysilanes. Finally, a mechanistic study demonstrates that the silane and the catalyst generate a Co–H species in the course of the reaction, which has been observed by in situ Raman spectroscopy.

Alkene hydrosilylation is typically performed with Pt catalysts, but inexpensive base-metal catalysts would be preferred. We report a Co catalyst for anti-Markovnikov alkene hydrosilylation that can be used without added solvent at low temperatures with l
