Evidence for concerted extrusion of TeR2 from permethylscandocene tellurolates
Abstract
Use of stereochemical probes shows that both the formation of permethylscandocene tellurolates (via tellurium insertion into Sc–C bonds) and the decomposition of permethylscandocene tellurolates (via extrusion of TeR2) proceed with retention of configuration in the probe, implying concerted transition states for both reactions.
