Abstract
The acidic decomposition of 4-acetylsydnones arylhydrazones 2 results in th e formation of 4-arylhydrazo-1,2-pyrazolin-5-ones 3 and 4-arylamino-1,2,3-t riazoles 4, respectively. The reactions of 4-acetylsydnones 1 with arylhydr azines 5 afford compounds 3 as the only products in the absence of solvent.
