Electrophilic Addition of Disulfur Dichloride to Alkynes, IV1). - Some Derivatives of the (1:1)-Adducts of Disulfur Dichloride and AlkynesIn dimethylformamide, which serves as a solvent and a catalyst, disulfur dichloride adds to alkynes to yield both divinyl sulfides and benzothiophenes. After oxidation of the resulting sulfides to the corresponding sulfones, the chlorine atoms located on the vinyl groups can be substituted by other nucleophilic agents.
Notes:
Dischwefeldichlorid addiert sich an substituierte Alkine unter Dimethylformamid-Katalyse und bildet sowohl Divinylsulfide als auch Benzothiophene. Nach Oxidation der Sulfide zu den entsprechenden Sulfonen können die vinylständigen Chloratome durch andere Nucleophile substituiert werden.
