Chalcogen atom transfer reactions. Kinetics of terminal bonded sulfur atom transfer between main group metal centers
Abstract
The first comprehensive investigation of S atom transfer between 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 atom transfer between [CyNC(tBu)NCy]2Ge and PPh3 are also presented.
