of the inherently large barrier to rotation and the resultant thermal decomposition pathway is discussed. Both phenomena are shown to be solvent independent; hinderedrotation is substrate independent. The decomposition of 1a is ca. 7 kcal/mol higher than the barrier to rotationabout the S−S bond. The combined evidence suggests acyclic unsymmetric homolytic cleavage of the dialkoxy disulfide.
