Flash vacuum pyrolysis (FVP) of 1-(2-arylhydrazono)-1-(1H-1,2,4-triazol-1-yl)acetone 8a-c at 650ยฐC 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 8Hbenzo[4
Flash vacuum pyrolysis of phenylazonaphthols and nitrosonaphthols at 7008C and 0.02 Torr yielded quinoline, isoquinoline, indene and naphthols (and aniline only from the phenylazo derivatives). Similar FVP of p-nitroso and p-phenylazophenol gave pyridine. Also, FVP of phenanthraquinonemonophenylhydr
