Under thermal activation in solution, N-[2-(1,3-oxathiolan-2-yl)]phenyl ketenimines and carbodiimides were converted into 2,1-benzisothiazol-3-ones bearing a pendant N-styryl or imidoyl fragment, respectively. These processes should occur with the concomitant formation of ethylene as result of the fragmentation of the 1,3-oxathiolane ring.
