ESR spectra of phosphonylthio-substituted ethyl radicals


  1. 1.

    An ESR study of phosphonylthio-substituted thioethyl radicals indicated the favored conformations and gave the barriers and enthalpies of the transitions between these conformations.

  2. 2.

    A synchronous mechanism was proposed for the rotation of the hindered methyl and thiophosphonyl groups in the conformational transitions in these radicals.
