摘要：

The reaction of [RuCp(L)(CH3CN)(2)]PF6 (L = CH3CN, PMe3) with (E)-N-(phenylmethylene)-2-pyridinamine (py-N=CHPh) affords the cyclic aminocarbene complexes [RuCp(L)(=CPhNH-py)]PF6, whereas with L = PPh3, CO the reaction stops already at the stage of the imine complex [RuCp(L)(kappa(2)N,N-py-N=CHPh)]PF6. This reaction arguably does not proceed via a direct 1,2-hydrogen shift but seems to involve hydrido iminoacyl intermediates as a result of C-H bond activation and deprotonation steps.
