Flash vacuum pyrolysis (FVP) of 1-(2-arylhydrazono)-1-(1H-1,2,4-triazol-1-yl)acetone 8a-c at 650Β°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 1,2βdialkoxybenzenes 1aβc leads to the liberation of alkanes from the interacting side chains. A rearrangement of the skeleton yields the __o__βhydroxy carbonyl compounds 2 and 4. The generation of phenol 3 can be rationalized by a decarbonylation. The latter r
The temperature dependence of products formed from flash vacuum pyrolysis (FVP) of 2-mercaptonicotinic acid 4 has been studied. FVP of 4 at 550Β°C and ca. 1Γ10 -2 torr gave pyridothietone 3b and a trimer 5 as the major products. At higher temperature (800Β°C), FVP of 4 gave 2-mercaptopyridine 6 as the
