Popis:	Flash vacuum pyrolysis (FVP) of 1-(2-arylhydrazono)-1-(1H-1,2,4-triazol-1-yl)acetone 8a-c at 650 °C and 2.67 Pa yielded 5-substituted 1-(1H-indazol-3-yl)ethanone 14a-c and 4,6-disubstituted cinnoline 18a-c. Similarly FVP of 1-(1H-benzo[d]imidazol-1-yl)-1-(2-phenylhydrazono)acetone 9a-c gave 8H-benzo[4′,5′]imidazo[2′,1′:5,1]pyrrolo[2,3-c]cinnoline derivatives 23a-c. A plausible mechanism is suggested to account for their transformation based on the kinetics and products of reaction.
