These reactions are extremely sensitive to conditions, e.g., temperature, solvent, etc. The best one is the reaction of the palladium complex (XXXVII) with iron pentacarbonyl to give (XIII). At 80° C the yield ranges from 87% in benzene, cyclohexane, or 1,2-dichloroethane, to 17% in tetrahydro-furan-diglyme and is zero in carbon tetrachloride (77). The reaction of (XXXVII) with molybdenum hexacarbonyl only occurs in aromatic hydrocarbon solvents and since the complex (XL) is obtained in the same yield starting from either molybdenum hexacarbonyl or benzenemolyb-denum tricarbonyl, it is reasonable to assume the latter to be an intermediate in this reaction.
