L’Abbe, Geuit published the artcileSynthesis of symmetrical 1,6-dihetero-6aλ4-thia-3,4-diazapentalenes from 5-amino-1,2,3,4-thiatriazole, Product Details of C2H8Cl2N4S2, the publication is Bulletin des Societes Chimiques Belges (1981), 90(1), 89-98, database is CAplus.
The dioxathiadiazapentalenes I (R = Ph, Me, CH:CH2, p-O2NC6H4, etc.) and tetraazathiapentalenes II (R1 = R2 = Ph, R = Me2CH, R1 p-MeC6H4; R1 = p-MeOC6H4, R2 = Me) were prepared by reactions of 5-amino-1,2,3,4-thiatriazole with RCOCl and R1CCl:NR2, resp. I and II exhibit no bond resonance. The thiadiazolinium salts III were intermediates in formations of II and subsequently reacted with a 2nd equiv of R1CCl:NR2. In the presence of base III decomposed into R2NHCR1:NCN. I reacted with P2S5 to give the diazatrithiapentalenes IV (R = Ph, Me3C, Me2CH).
