Analogies between the dynamic stereochemistry at silicon and phosphorus. Kinetic study of solvent-induced epimerisation of menthyl chloro(phenyl)phosphonate

Abstract

A kinetic study of the solvent-induced epimerisation of menthyl chloro(phenyl)phosphonate shows an overall third-order process, first-order in chlorophosphonate and second-order in nucleophilic agent; activation parameters are consistent with a mechanism involving extension of co-ordination at phosphorus which is similar to that for silicon compounds.
