摘要
[(HC = CCH2)Co2(CO)6]BF4 (1) and [(HC = CCH2)Mo2(C5H5)2(CO)4]BF4 (2) react with primary and secondary amines in CH2Cl2 solution. In the case of primary amines, the products of mono and dialkylation are obtained. The more stable (less reactive) molybdenum complexes can be employed to alkylate amines in a protic, two-phase medium. The results are interpreted mechanistically and shown to dependent on the thermodynamic stability of the metal-stabilized carbocation.
