Phosphorous-substituted redox-active ligands in base metal hydrosilylation catalysis

This article highlights the utilization of phosphine-containing redox-active ligands for efficient hydrosilylation catalysis. Manganese, iron, cobalt, and nickel precatalysts featuring these chelates have been described and leading activities for carbonyl, carboxylate, and ester C-O bond hydrosilylation have been achieved. Mechanistic studies have provided insight into the importance of phosphine hemilability.
