Reversible electrochemical reduction of 1,6,6a-trithia-3,4-diazapentalenes to their anion radicals with the production of superoxide

1,6,6a-Trithia-3,4-diazapentalenes, which are hypervalent compounds, were reduced electrochemically and the resulting anion radicals reacted with dioxygen (O2) to be re-oxidized to the starting materials, with the production of superoxide (O2-.). We have already reported that 1,6-dioxa-6a-thia-2,5-diazapentalenes mediate O2-. production in living cells and do serious damage to the cells. These results suggest that hypervalent heteropentalenes generally generate O2-. in the presence of O2 by chemical or biological reduction system.

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.

SYNTHESIS OF SYMMETRICAL 1,6-DIHETERO-6aλ4-THIA-3,4-DIAZAPENTALENES FROM 5-AMINO-1,2,3,4-THIATRIAZOLE

1,6-Dioxa-6aλ4-thia-3,4-diazapentalenes 7 and 1,3,4,6-tetraaza-6aλ4-thiapentalenes 15, two new classes of compounds with single bond - no bond resonance, have been prepared by reaction of 5-amino-1,2,3,4-thiatriazole 4 with acyl chlorides and imidoyl chlorides.In the latter case, the salts of 5-imino-Δ3-1,2,4-thiadiazolines 12 were first isolated and subsequently reacted with a second equivalent of imidoyl chloride.This also led to the synthesis of unsimmetrically substituted 1,3,4,6-tetraaza-6aλ4-thiapentalenes.In the presence of bases, the salts 12 decompose via the isolable free bases 13 into N-cyanoamidines 14 and sulfur.Treatment of the dioxathiapentalenes 7 with P4S10, or direct thiobenzoylation of 4 gave the 3,4-diaza-1,6aλ4-trithiapentalenes 9.
