of S atomtransferbetween two different metal centers is presented using the reaction of the terminal chalcogen atom bearing complex [CyNC(tBu)NCy]2SnS with [CyNC(tBu)NCy]2GeII; this multielectron redox reaction between GeII and SnIV proceeds via a second-order process with an inner sphere mechanism involving a μ-S intermediate as the proposed pathway; results of S and Se atomtransferbetween [CyNC(tBu)NCy]2Ge
使用末端含硫原子的络合物 [CyNC(tBu)NCy]2SnS 与 [CyNC(tBu)NCy]2GeII 的反应,首次全面研究了两个不同金属中心之间的 S 原子转移;GeII 和 SnIV 之间的这种多电子氧化还原反应通过二级过程进行,内球机制涉及 μ-S 中间体作为建议的途径;还给出了 [CyNC(tBu)NCy]2Ge 和 PPh3 之间的 S 和 Se 原子转移的结果。
