Thermolysis of tetramethylallene episulfide() gave 2,4-dimethyl-3-mercaptopenta-1,3-diene() via thioxyallyl intermediate() by unimolecular C-S bond cleavage. 3,3,5,5-Tetramethylpyrazoline-4-thione () also gave probably via the same intermediate(), which has a biradical character.
A variety of sulfur-containing five- and six-membered cyclic compounds was obtained by the acid-catalyzed and thermal reactions of an allene episulfide with various electrophiles.
