摘要

Abstract The cyclisation of η p1-alkyl-γ-allenic ligands of iron complexes into η 2- allylcyclopentenone ligands has been achieved. As reaction intermediate an η 1-acyl-η p2- allenic chelate is characterised, which gives the cyclic product. The ring closure is viewed as a cis migration. suggesting a concerted pathway in the reactions where an/gh p2-allenic ligand is converted into an η p3-allyl ligand.
