“…Therefore, special attention was paid to the development of efficient and reliable methods for the synthesis of 3H-1,2-dithiole-3-thiones and to their reactivity. A number of reviews deal with the general aspects of the chemistry of 1,2-dithioles, such as the corresponding chapters in Comprehensive Heterocyclic Chemistry II and III [22,23] and other reviews that should be ranked among the most important ones [24][25][26]. No special review dedicated to the synthesis and reactivity of 3H-1,2-dithiole-3-thiones was previously available in the literature.…”

3H-1,2-Dithiole-3-thiones are among the best studied classes of polysulfur-containing heterocycles due to the almost explosive recent interest in these compounds as sources of hydrogen sulfide as an endogenously produced gaseous signaling molecule. This review covers the recent developments in the synthesis of these heterocycles, including both well-known procedures and important novel transformations for building the 1,2-dithiole-3-thione ring. Diverse ring transformations of 3H-1,2-dithiole-3-thiones into various heterocyclic systems through 1,3-dipolar cycloaddition, replacement of one or two sulfur atoms to form carbon- and carbon-nitrogen containing moieties, and other unexpected reactions are considered.

A practical and straightforward strategy for the synthesis of 3-acylimino-3H-1,2-dithiol derivatives via a metal-free annulation reaction of alkynylnitriles with thiocarboxylic acids mediated by ionic liquids [BMIM]Br has been reported. This operationally simple protocol offers an easy and rapid access to a library of dithiol derivatives in moderate to good yields. The mechanistic studies show a benzoyldithio anion addition to alkynylnitriles followed by an annulation reaction through the involvement of a disulfide moiety as the key intermediate.
