β -Propiothiolactones are cleaved at the S-CO bond by methanesulfenyl chloride and acetyl sulfur chloride to form mixed disulfides — derivatives of the acid chlorides of β -mercapto-isobutyric acid. The mixed disulfides readily disproportionate on heating under acid or base catalysis conditions to give the corresponding symmetrical disulfides. A convenient method was found for obtaining the previously hard-to-obtain symmetrical disulfides.
