Popis:	N-Thiocarbonyl diphenylsulfimides, Ia–i (R=Ph, p- and m-MeC6H4, p- and m-MeOC6H4, MeO, EtO, MeNH, and Me2N), were prepared, and their thermal decomposition were studied. At 70 °C, Ia–h decomposed easily to give nitriles (or their derivatives), together with diphenyl sulfide and sulfur. Contrary to these results, the oxygen analog of Ia, g showed no decomposition even upon heating at 140 °C. The thermolysis of Ia–e in the presence of excess acetylenes (III) gave isothiazoles(IV) in moderate yields. Thiazirine(V) and nitrile sulfide(VI) may be supposed, on the basis of the kinetic experiments, to be possible intermediates for the thermal decomposition of Ib–e.
