Ion pairing with cations has a marked but nonuniform effect on the chemistry of carbonylmetalate anions and can either inhibit or facilitate their reactions. A study of the effect of cation-solvating agents ([18]crown-6, hexamethylphosphoramide) on the reactions of carbonylmetalates [Na(K)][M(CO)n L] with vinyl halides activated with strong electron-withdrawing groups, which at the same time could
