文摘

Addition of a Grignard reagent to keto-substituted (η⁵-cyclohexadienyl)Mn(CO)₃ complexes leads to the corresponding alcohols in very good yields. After acidic treatment, dehydration occurs, which gives rise to the formation of unprecedented (η⁵-cyclohexadienyl)Mn(CO)₃ complexes substituted by a double bond conjugated to the π system as the major compounds, along with uncoordinated trienones due to the rearrangement of the intermediate carbocation. The structure of one of these η⁵ complexes has been determined by X-ray crystallography as well as one of the corresponding cationic (η⁶-arene)Mn(CO)₃ complexes formed upon hydride abstraction.
