(Y = Cl, Br, I; R = H or Me) or YCMe2CCCMe2Y were prepared from their diol precursors and reacted with [Mo(CO)3(phen)Y]− (phen = 1,10-phenanthroline) in chlorinated solvent, methanol or water. Formation and stability of substituted products of the type [Mo(CO)2(η3-CH(R)C(COX)CCH(R))(phen)Y] (X = Y or X = OMe) were found to be dependent upon the nature of the halogen and degree of alkyl substitution
