Synthetic studies on the reactions of hydrazine and aroylhydrazide with 5-phneyl-1,3,4-oxadiazol-2-thione

The reaction of 5-phenyl-1,3,4-oxadiazol-2-thione 1 with hydrazine hydrate in refluxing n-butanol afforded benzoylcarbohydrazide 2 which was cyclized to 4-amino-3-chloro-5-phenyl-1,2,4-triazole 3. Compound 3 was used for the synthesis of some new di-or polyheterocyclic derivatives via its reaction with anilines and treating the products with bidentates.

2-(Substituted hydrazino)-5-phenyl-1,3,4-oxadiazoles react with bromine in acetic acid to yield hydrazone perbromides, or hydrazonyl bromides in the presence of sodium acetate. Treatment of the hydrazonyl bromides with triethylamine in benzene or solvolys
