【摘要】 In the study of N-H functionalization,the activation of N-H bond by transition metal complex played an important role in the formation of N-C bond.¹ We once reported the activation of C_sp3-H bond in[PCP]-type pincer ligand assisted by Fe complex and explored its catalytic activity in hydrosilylation of aldehydes and ketones.² We attempted to investigate the catalytic activity of[PNP]-pincer complex based on N-H activation.By the reaction of[PNP]-ligand 1 with Fe（PMe₃）₄ and Ni（PMe₃）₄,we isolated the N-H activation product 2 and simple coordination complex 3.From the reactions of 1 with CoMe（PMe₃）₄,Co（PMe₃）₄ and CoCI（PMe3）3,the same product 4 was isolated.In order to have a better understanding of the reaction mechanism,we conducted the in situ IR and NMR detections to verify the formation of intermediates 4a and 4b.更多还原
