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]₂Ge^II; this multielectron redox reaction between Ge^II and Sn^IV 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.
