Electrophilic addition of the carbene ligand in [Fe(CO)2(η5-C5H5){=CMe(OMe)}]+ to the reductively activated benzene ligand in [Mn(CO)3 (η4-C6H6)]-

The iron carbene cation [Fe(CO)(2)(eta(5)-C5H5)-{=CMe(OMe)}](+) reacts with reductively activated [Mn(CO)(3)(eta(4)-C6H6)](-) to form the carbene/benzene adduct [Mn(CO)(3){eta(5)-C6H6-CMe(OMe)Fe(CO)(2)(eta(5)-C5H5)}] (3). Reduction of 3 is proposed to give species in which there are ferrocyclic benzene-derived ligands.
