Bulking up: The thermal barrier to rearrangement of a vic ‐disulfoxide is significantly increased through steric buttressing about the (O)SS(O) bond. Whereas the title compounds represent the most thermally stable vic ‐disulfoxides known to date, they also undergo a novel photomediated epimerization at room temperature (see scheme).
