Reactions of 2,3-Disubstituted 6,7-Dihydro-5H-2a-thia(2a-SIV)-2,3,4a,7a-tetraazacyclopentindene-1,4(2H,3H)-dithiones with Isothiocyanates and Isocyanates

12?-Tetraazapentalenes, 2,3-disubstituted 6,7-dihydro-5H-2a-thia(2a-SIV)-2,3,4a,7a-tetraazacyclopentindene-1,4(2H,3H)-dithiones, 1 and 7, reacted with excess alkyl or aryl isothiocyanates and isocyanates to afford mono- and di-alkyl or aryl substituted tetraazapentalene derivatives which have the thiocarbonyl and carbonyl groups.

Synthesis of novel tetraazapentalene derivatives (10-S-3) with a hypervalent sulfur and carbonyl groups

Tetraazapentalenes (R=CH3 and CH2=CHCH2) reacted with isocyanates to give new types of tetraazapentalenes, (2) and (3).The compounds, 2 and 3, were also obtained by the reaction of isocyanates with thiadiazolopyrimidines.
