Three bis-bridged diiron species, μ,μ1-(1-X-2-Y-benzene)hexacarbonyldiiron [X = Y = PPh (3a); X = S, Y = PPh (3b); X = Y = S (3c)], have been prepared by the thermal reaction of the corresponding dihydro forms of the ligand and excess nonacarbonyldiiron. Reduction of 3a-c with 2 equiv of electrons gives rise to a dianton in which cleavage of an Fe-X bond has occurred in contrast to the reductive behavior of (μ-PPh2)2Fe(CO)6 which cleaves an Fe-Fe bond. The dianion derived from 3a reacts with excess trifluoracetic acid to give the phosphorus and iron-protonated species. Methylation (MeI) of (3a)2- gave a complex with the structure assigned as [1-P(Me)Ph-μ-2-PPhC6H4] [μ-C(O)Me] (CO)5Fe2. An analogous complex was obtained on methylation of (3b)2-.
