Elfahham, Hassan A. published the artcileThe reactions of nitrile imines with amino- and oxo-substituted azoles, Name: 5-Phenyl-1H-pyrazol-3(2H)-one, the main research area is azole reaction nitrile imine hydrazonyl halide; pyrazole cyclization hydrazonyl chloride; pyrazolopyrazole; pyrazolotriazole; azatricycloundecanone; adamantanone oxime rearrangement.

The behavior of several amino and hydroxy azoles toward nitrile imines and hydrazonyl halides is reported. Thus, the pyrazoles I (R = Ph, R1 = H2N, OH) reacted with PhCCl:NNHPh to give the pyrazolopyrazole II. I (R = Me, R1 = OH) under identical conditions gave the pyrazolotriazole III. I (R = Ph, R1 = NH2) reacted with MeCOCCl:NNHPh to give the pyrazoloimidazole IV.
