Four new N-heterocyclic carbene (NHC)–rhodium and iridium complexes derived from 2,2′-diaminobiphenyl have been successfully synthesized and their structures have been unambiguously characterized by X-ray diffraction. Their catalytic activities for hydrosilylation of ketones with diphenylsilane were investigated. It was found that NHC–rhodium complex (6) is the best one among the four catalysts for
