1,1',2,2'-Tetrathiafulvalenes, IV. - On the Reactions of Cyclopropen(thio)nes with 1,2-Dithiole Compounds: Thienothiophenes, Thienofurans, 4H-Furopyrroles, 1,2-Dithiole-3-(thi)ones, and other Heterocycles Containing Sulfur

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.
