Bis-(η⁴-1,5-cyclooctadiene)nickel(0) reacted with η⁵-C5H5Fe(CO)2Cl, η³-C5H5Fe(CO)3Cl, Mn(CO)5Cl and (CO)4>2 to form metal-metal bonded coupling products.Partial reduction of Mn(CO)5Cl gave 2 shown to have a chlorine-bridged C_2h structure by X-ray diffraction analysis.Ligand transfer also accompanied the reduction of Fe2(CO)2Br2 and Fe(CO)4Cl2 to Fe2(CO)3 and Fe(CO)5, respectively.Only partial reduction was observed for Ti(acac)2Cl2 and (η⁵-C5H5)2TiCl2 which gave 2 and (η⁵-C5H5)2Ti(py)Cl, respectively.
