The cyclisation of ηp1-alkyl-γ-allenic ligands of iron complexes into η2-allylcyclopentenone ligands has been achieved. As reaction intermediate an η1-acyl- ηp2-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 /ghp2-allenic ligand is converted into an ηp3-allyl ligand.
η的环化P1铁络合物的烷基- γ-丙二烯配位体为η 2 -allylcyclopentenone配体已经实现。作为反应中间体的η 1 -acyl-η P2 -allenic螯合物的特征,这使环状产物。闭环被视为顺式迁移。这表明在一个/ GH反应协调一致通路P2 -allenic配体被转换成η P3 -烯丙基配体。
