The present study emphasizes on the dealklylation of 3-aryl-5-alkyl-2-oxo-Δ4-1,3,4-oxadiazoles when reacted with formamide resulting in the formation of 2-aryl-2H-1,2,4-triazol-3(4H)-ones as major product. Subsequent reactions of 2-aryl-2H-1,2,

The reaction of acetone arylhydrazones with acetyl isocyanate gave the corresponding 4-acetyl-1-aryl-3,3-dimethyl-1,2,4-triazolidin-5-ones which eliminated acetone upon hydrolysis to give 1-aryl-3-methyl-1,2,4-triazolin-5-ones.The above transformation can be achieved in one pot by a simple solvent swap.
