An aryl diimine cobalt(i) catalyst for carbonyl hydrosilylation. Issue 77 (8th September 2022) - Sharma, Anuja
Abstract : Aldehyde and ketone hydrosilylation turnover frequencies of up to 330 s −1 have been achieved using a phosphine-substituted aryl diimine cobalt catalyst. Abstract : Through the application of a redox-innocent aryl diimine chelate, the discovery and utilization of a cobalt catalyst, ( Ph2 PPr ADI)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.
