A new synthesis method was established for 1,2-dithiol-3-ones and 1,2-dithiol-3-thiones, from different cyclopropenones: diphenyl (a), bis-(4-methoxyphenyl (b), diferrocenyl (c) and diruthenocenyl (d), in the presence of elemental sulfur with yields of the 5a-d (35–57%), or in the presence of the additive NaHS, with yields of the 5a-d (45–72%) and 6a-d (10–18%). The characterization of the new compounds was conducted by IR, 1H and 13C NMR spectroscopy, elemental analysis, mass-spectrometry. In addition, X-ray crystallographic analysis of the compounds 5a,b,d was conducted. The redox properties of the heterocyclic compounds were investigated using cyclic (CV), differential pulse (DPV) and square wave (SWV) voltammetries.

4,5-Disubstituted 1,2-dithiole-3-thiones (1,2-trithiones) 1 react with 2,3-diphenylcyclopropenethione (2a) to give by elimination of two atoms sulfur thienothiophenes 5.The reaction of 1a with 2a yields in addition tetraphenylthieno-1,2-dithiin (6a). 1,2-Trithiones react with 2,3-diarylcyclopropenones 7 (R3=Aryl) to give the corresponding thienofurans 8 and 1,2-dithiole-3-ones 9. - In 4-position unsubstituted 5-aryl-1,2-trithiones and 2,3-diarylcyclopropenones 7 (R3=Aryl) react in a more complex manner.In the reaction of 4,5-disubstituted 3-phenylimino-1,2-dithiole-3-thiones 18 with 7 (R3=Aryl) 4H-Furopyrroles 19 are formed. - Furthermore it will be reported on conversions of 5-phenyl-3H-1,2,4-dithiazole-3-thione (24), 2-benzyl-4-methyl-3-phenyl-1,2-thiazole-5(2H)-thione (27a), and 2-benzyl-4-phenyl-1,2-thiazole-5(2H)-thione (27b) in the reactions with the cyclopropenones 7d respective 7a.
