The reaction of the Fe2(CO)82- dianion with methylene iodide leads to the formation of the parent bridging methylene complex, octacarbonyl(μ-methylene)diiron, Fe2(CO)8CH2. The reaction appears to be general and several derivatives have been prepared by using other geminal diiodides. The bridging methylene complexes react with unsaturated reactants such as olefins and acetylenes to produce new organometallic complexes in which the unsaturated molecule has inserted between the methylene ligarid and an iron atom. With hydrogen, the complexes react to produce the dihydro form of the methylene ligand; nucieophilic reagents such as iodide ion, alcohols, and water appear to attack a Co ligand with subsequent rearrangement involving the bridging methylene group.
