Dinitrogen loss from a range of bis(N2)-complexes of Mo and W is the common rate-determining step in the primary alkylation of the remaining co-ordinated N2, whereas the second alkylation of co-ordinated N2 is a typical SN2 reaction; the rates of these reactions are sensitive to both the metal and the coligands, and those factors which encourage the first alkylation are those which inhibit the second
从一系列双(N的二氮损失2的Mo)-complexes并且W是在初级烷基化的共同速率决定步骤剩余的协调Ñ 2,而互相配合的n中的第二烷基化2是一个典型的S N 2反应;这些反应的速率对金属和大肠菌素均敏感,而那些促进第一个烷基化的因素就是那些抑制第二个烷基化的因素。
