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 8Hbenzo[4
## Abstract Flash vacuum pyrolysis of 1,2‐dialkoxybenzenes 1a‐c leads to the liberation of alkanes from the interacting side chains. A rearrangement of the skeleton yields the __o__‐hydroxy carbonyl compounds 2 and 4. The generation of phenol 3 can be rationalized by a decarbonylation. The latter r
