5-1,2,3,4,5-PENTAKIS(CARBOMETHOXY)CYCLOPENTADIENYL>TRICARBONYLMANGANESE(I): SYNTHESIS, SPECTROSCOPY AND REACTIVITY

Article abstract of DOI:10.1016/0022-328X(84)80092-3

Treatment of the potassium salt of pentakis(carbomethoxy)cyclopentadiene with bromopentacarbonylmanganese(I) gives pentakis(carbomethoxy)cyclopentadienyltricarbonylmanganese(I) in good yield.Photochemical substitution of a metal carbonyl group by tributylphosphine, triphenylphosphine and triethyl phosphite is reported.Attempts to modify the ester function are described; hydrolysis or amination give mixed products but reduction with lithium aluminum hydride yields ultimately the pentamethylcyclopentadienyl complex.
