Reactivity of Keto-Substituted (η5-Cyclohexadienyl)Mn(CO)3 Complexes toward Hydrides
摘要:
Reaction of hydrides with (eta(5)-ketocyclohexadienyl) Mn(CO)(3) complexes yielded the corresponding alcohols as major products but also cyclohexadienes due to the addition of hydride to the C-2 carbon of the C-1-C-5 pi-system. This unexpected regioselectivity has been established by different labeling experiments. The structures of one of the starting keto-substituted (eta(5)-cyclohexadienyl) Mn(CO)(3) complexes and its corresponding alcohol have been determined by X-ray crystallography.
