Sulfenylating reagents have been obtained by the action of sulfuryl chloride or antimony pentachloride on di(2-pyridyl) disulfide. Their interaction with alkenes proceeds as addition-cyclization with ring closure by the nitrogen atom of the pyridine fragment of the sulfur-containing electrophile with the formation of 2,3-dihydro[1,3]thiazolo[3,2-a]pyridinium derivatives.
