  Generation of α-Phosphinocarbene Complexes and Their Evolution: New Light on Relevant Isomerization Pathways

  摘要：

  The eta(1)-alpha-phosphinocarbene complex CP(CO)(2)Mn=CR(PHMes) (R = Ph, Me) is generated by nucleophilic attack of MesPH(2) at the electrophilic center of the cationic Mn-carbyne complex [Cp(CO)(2)Mn CR](+), followed by deprotonation. One of its identified isomerization pathways to eta(1)-phosphaalkene derivatives is shown to be both base-catalyzed and stereoselective, and to involve a transient phosphidocarbene species engaged in an acid-catalyzed migratory CO-insertion step.
