Abstract Reaction of pentacarbonylmanganese tetrafluoroborate with veratrole (1, 2- dimethoxybenzene) affords η 6-veratrolemanganese tricarbonyl tetrafluoroborate in 66% yields. This complex does not react satisfactorily with alkyllithium compounds, but it does undergo highly regioselective reaction with the lithium enolate of cyclohexanone, ortho to the MeO substituent. The product was converted to 2-(2, 3-dimethoxyphenyl) ...
