Reactivity of amidrazones : Synthesis of New Spiro 4,5-dihydro-1,2,4-triazole and 1,2,4-triazole derivatives

الملخص EN

Nucleophilic substitution reaction of hydrazonoyl chlorides with ammonia, methyl amine and 4-chloroaniline gave the corresponding amidrazones.

Treatment of amidrazones with cyclic and acyclic ketones and benzaldehyde in the presence of acid as a catalyst gave 4, 5-dihydro-1, 2, 4- triazoles and 1, 2, 4-triazoles respectively.

The structures of the synthesized compounds have been confirmed by the elemental analyses and spectroscopic data (IR, MS, 1H NMR and 13C NMR.)
