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

Article abstract of DOI:10.1246/cl.1989.39

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.
