Abstract

The behavior of binuclear “ladder” type complexes FpL, where Fp=Cp(CO)2Fe, L=p-MeC6H4Cr(CO)3 (4), CH2C6H5Cr(CO)3 (5), andp-FpC6H4Cr(CO)3 (6), under conditions of metallation was studied. Unlike compounds5 and6, the σ-bound ligand L in compound4 migrates from the iron atom to the cyclopentadienyl ring to give complexes Me(CO)2FeC5H4−C6H4(p-Me)Cr(CO)3. The electrochemical reduction potentials of the complexes4–6 and the rearrangement products were measured. The migration activity of L is determined by the ease of reductive cleavage of the Fe−L bond and the susceptibility of the system to undergo intramolecular electron transfer from the Cp ligand to the aromatic ring.
