The reactions of nitrile oxides or nitrile imines with pyrazole, imidazole, 1,2,3- and 1,2,4-triazole or tetrazole derivatives yield the appropriate N-hydroximoyl- or N-hydrazonoylazoles.Thermolysis of 1-hydroximoyltetrazoles, depending on the nature of the substituents in the tetrazole ring, yields 1,2,4-oxadiazoles or 5-amino-1,2,4-oxadiazoles upon hydrazoic acid or nitrogen evolution.Under similar conditions, 1-hydrazonoyltetrazoles give 1,2,4-triazoles or 5-amino-1,2,4-triazoles while 2-hydrazonoyltetrazoles decompose to the dihydro-1,2,4,5-tetrazine derivatives.
