Abstract
Hydrazonoyl halides (1) react with alkanone and cycloalkanone alkoxycarbonylhydrazones (3) to give the cycloaddition products 4,5-dihydro-1,2,4-triazoles (7a–h) rather than the tetrazine cyclocondensation products. Reaction of (7c,d) with hydoxylamine gave the corresponding oximes (8c,d) of these heterocycles.
