Reaction of 2-triphenylphosphoimino-1-azaazulenes (4a-c), prepared from 2-amino-1-azaazulenes, with some aryl isocyanates gave 2-arylimino-3-aryl-2,3,4,4a-tetrahydro-1,3,4a-triazabenz[a]azulen-4-one (6) as major products. Reaction of aryl isothiocyanates

3-Phenyl- and 3-(4-nitrophenyl)cyclohepta[4,5]pyrrolo[1,2-a]-1,3,5-triazine-2,4(3H)-diones and the corresponding arylimino derivatives (5a,b) and (6a,b) were synthesized by the reaction of (1-azaazulen-2-yl)iminotriphenylphosphorane with aryl isocyanates

Reaction of 2-amino-1-azaazulene with phenyl isocyanate gave 3-phenyl-2H-3,4-dihydro-1,3,4a-triazabenz[5,4-a]azulene-2,4-dione. Reactions of 2-alkylamino-1-azaazulenes with aryl isocyanates gave 2-(N-ethyl-N-arylureido)-1-azaazulenes initially, which rearranged to N-aryl-2-alkylamino-1-azaazulene-3-carboxamides and successive reaction with another molar amount of aryl isocyanate furnished uracil-fuzed 1-azaazulenes. Reaction of 2-piperidino-1-azaazulene with aryl isocyanate gave N-aryl-2-piperidino-1-azaazulene-3-carboxamide. Reaction of 2-(substituted amino)-1-azaazulenes with chlorosulfonyl isocyanate gave 3-cyano- and 3-chloro-2-(substituted amino)-1-azaazulenes.
