N-Methylimidazole (NMI) can act as a masked HCN in the synthesis of 1,3-disubstitued-1H-1,2,4-triazoles via a formal cycloaddition reaction of hydrazonoyl chloride with NMI. The product was proved to be formed via an initial nucleophilic substitution of hydrazonoyl chloride with NMI following cyclization and two sequential C-N bond cleavages. This journal is

Aliphatic and aromatic hydrazides have been prepared in high to moderate yields by a direct condensation reaction of aliphatic or aromatic carboxylic acids with hydrazine or phenylhydrazine using phosphorous acid-iodine as reagent and pyridine as base and solvent. With aliphatic carboxylic acids, we obtained good results heating at 80-90°, for 5-6 hours, but with aromatic carboxylic acids are necessary 140-150°, for the same period of time.
