Hydride reduction of tricarbonylarenemanganese cations gives, in addition to the known cyclohexadienyl compounds, appreciable yields of dicarbonylarenemethylmanganese by direct reduction of a metal carbonyl group. Alkyllithiums also attack the cations at carbonyl groups as well as at the ring carbons and, in the case of polyalkylbenzene complexes, fair yields of acyl derivatives result. These may be decarbonylated photochemically and may also be converted to cationic carbene complexes by alkylation with triethyloxonium tetrafluoroborate.
