[C5H5Fe(1,4-(CH3)2C6H4)]PF6 undergoes photochemical p-xylene substitution in nitrile (RCN) solution in the presence of two equivalents of phosphorus donor ligands L upon UV-vis irradiation at λmax ⩾ 300 nm (R = CH3, C2H5, n-C3H7; L = P(OCH3)3 or 12[(C6H5)2PCH2]2). High yields of [C5H5Fe(L2)NCR]PF6 complexes are obtained. Thermal substitution of the coordinated nitrile ligand RCN in these complexes
