Electron transfer catalysis of arene deco-ordination in the cationic (η5-cyclopentadienyl)(η6-arene)iron(II) complexes
Abstract
Replacement of the arene group in [Fe(η5-C5H5)(η6-C6H6–n-Men)]+(n⩽ 4) by three P(OMe)3 ligands is carried out under mild conditions by reductive electron transfer catalysis in acetonitrile and gives the free arene and [(η5-C5H5)Fe {P(OMe)3}3]+ in good yields.
