摘要：

Cationic metallacyclopentatriene complexes having an a-alkyl substituent undergo facile 1,2-hydrogen shift to give butadienyl carbenes. This is exemplified by the reaction of [RuCp(L)(CH3CN)(2)]PF6, where L = SbPh3, SbBu3n, and AsPh3, with 2,8-decadiyne, 1-hexyne, and benzylacetylene. There is an interesting mechanistic changeover on going to L = PR3, in which case PR3 migrates with an allyl carbene complex being formed.
