Abstract
Dihaloalkynes of the type YCH(R)CtripleCCH(R)Y or YCMe2CtripleCCMe2Y (Y=Cl, Br, I) were prepared from their diol precursors and reacted with [Mo(CO)3(phen)Y]-. Formation and stability of the substituted products of the type [Mo(CO)2(h3-CH(R)C(COX)C=CH2)(phen)Y] (X=Y or OMe) were found to be dependent upon the nature of the halogen and the degree of alkyl substitution of the alkyne. Reactions carried out in mixtures of methanol and ethers gave an alternative double addition product of the type [Mo(CO)2(h3-CH(R)C(CO2Me)C=C(OMe)(CH2R)(phen)Y] for R=H, Y=Cl only.
