Abstract
2, 5-Diaryl-3-alkyl-1, 3, 4-oxadiazolium salts react with hydrazine to give acyclic hydrazinolysis products or products of recyclization with participation of the carbon atom in the 2 position of the oxadiazole ring, i.e., dihydro-sym-tetrazines and N-amino-sym-triazoles (with hydrazine) and 2-phenyl-5-aryl-1, 3, 4-oxadiazoles (with benzoylhydrazine) or formazans (with phenylhydrazine).
