REACTION OF CARBOHYDRAZIDE WITH 1,2-DICARBONYL COMPOUNDS

Abstract

The reaction of carbohydrazide with 1,2-dicarbonyl compounds yields a series of ylidene derivatives, namely, mono- or bishydrazones, 5-hydroxy-, 5-alkoxy, or 5-methylene-4,5-dihydro-2H-[1,2,4]triazin-3-ones depending on the structure of the dicarbonyl compound and nature of the solvent.
