cleavage by iodine of tin-cobalt bonds in compounds [MenSnCo(CO)4}4−n] (n 0−3) and [Me2ISnCo(CO)4]. The reactions are rapid with k2ca. 0.3–3000 dm3 mol−1 s−1 in cyclohexane at 30°C. As the number of SnCo bonds increases the reactivity of the bonds decreases rapidly. Replacing a methyl group by a Co(CO)4 group has roughly the same effect on the reactivity of SnCo bonds as replacing a methyl group by
报道了化合物[Me n Sn Co(CO)4 } 4 - n ](n n 0-3)和[Me 2 ISnCo(CO)4 ]中锡-钴键碘裂解的速率系数。该反应是快速的与ķ 2约 在30°C下于环己烷中的0.3–3000 dm 3 mol -1 s -1。随着SnCo键数目的增加,键的反应性迅速降低。用Co(CO)4取代甲基该基团对SnCo键的反应性具有与用碘原子取代甲基基团大致相同的作用。动力学研究受到产物[Co(CO)4 I]的不稳定性的阻碍,该产物会迅速分解。
