Abstract

An ESR study of phosphonylthio-substituted thioethyl radicals indicated the favored conformations and gave the barriers and enthalpies of the transitions between these conformations.A synchronous mechanism was proposed for the rotation of the hindered methyl and thiophosphonyl groups in the conformational transitions in these radicals.
