An aryl diimine cobalt(i) catalyst for carbonyl hydrosilylation

Through the application of a redox-innocent aryl diimine chelate, the discovery and utilization of a cobalt catalyst, ((Ph)(2)PPrADI)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.11Nsciescopu
