is observed. Preliminary kinetic investigations of the related reactions with (1; M = Ru or Os) provide the first quantitative comparison of the reactivity of cyclohexadienyl rings when co-ordinated to each of the iron triad metals, namely Fe > Os > Ru (41 : 3.6 : 1).
                                    配合物[M(C 6 H 7)(CO)3 ] [BF 4 ](1; M = Fe,Ru或Os )根据方程(I )已显示出对NN-二甲基
苯胺(RH)的亲电性)。与[Cr(C 6 H 7)(CO)3 ] [BF 4 ]发生相似的反应。对于[M(C 6 H 7)(CO)3 ] [BF 4 ] + RH → [M(C 6 H 7 R)(CO)3 ] + HBF 4(I)(1; M = Fe)和[ Fe(C 6 H 6 OMe-2)(CO)3 ] [BF4 ]速率定律,观察到Rate = k [complex] [RH]。对与(1; M = Ru或Os)的相关反应进行的初步动力学研究提供了环
己二烯基环与每种三重
铁金属配位时的反应性的第一定量比较,即Fe> Os> Ru(41:3.6 :1)。
