The sense of bis(2-chloropropenyl)sulfide heterocyclization at its interaction with sulfur, selen and tellur in the hydrazine hydrate–KOH system has been studied. The suggest plausible mechanism of different heterocycles formation is discussed.
bis(2-chloropropenyl)sulfide, hydrazine hydrate–KOH, sulfur, selen, tellur, 1,4- dichalcogenins.
