Abstract
Abstract A series of ester formylhydrazones 2 were synthesized from the reaction of alkyl imidate hydrochlorides 1 with formylhydrazine. Treatment of 2 with hydrazine hydrate, ethyl carbazate and tert-butyl carbazate led to the formation of 3-alkyl-4-amino-, 3-alkyl-4- ethoxycarbonylamino-and 3-alkyl-4-tert-butoxycar-bonylamino-4H-1, 2, 4-triazoles 3–5, respectively. Reaction of compounds 2 with formylhydrazine gave N, N'-diformylhydrazine ...
