Abstract

Through the application of a redox-innocent aryl diimine chelate, the discovery and utilization of a cobalt catalyst, (^Ph₂PPrADI)Co, that exhibits carbonyl hydrosilylation turnover frequencies of up to 330 s^-1 is described. This activity is believed to be the highest ever reported for metal-catalyzed carbonyl hydrosilylation.
