Abstract The reactivity of a number of diphosphaferrocenes towards aluminium chloride in aromatic solvents has been investigated. Where the substrate contains a 2-acyl substituent, the ligand is cleaved and a η 6 -arene η 5 -phosphacyclopentadienyl iron(II) cation formed by reaction with the solvent. Two such novel cations have been isolated as their hexa- fluorophosphate salts and the π-bonded nature
