摘要：

Reanimation: Catalytically inactive π-allyl iron complexes are "reanimated" upon addition of N-heterocyclic carbene ligands such as 1,3-dimesitylimidazolin-2-ylidene (SIMES). A comparison of stoichiometric and catalytic allylic alkylation reactions shows the π-allyl mechanism to be active in this catalytic system. © 2009 Wiley-VCH Verlag GmbH & Co. KCaA.
