Domino reactions of alkane dithiolates with 2,3-dichloro-1-propene in hydrazine hydrate – KOH medium
摘要:
2,3-Dichloro-1-propene reacts with alkane dithiolates in hydrazine hydrate - KOH medium to produce derivatives of dithiin, dithiepin, chloropropenyl, and allenyl sulfides depending on conditions and dithiolate structure. The formation of the heterocyclic products is a result of possible domino reactions, including a substitution of an allylic chlorine atom, dehydrochlorination, and intramolecular heterocyclization.[GRAPHICS].
