Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry published new progress about Cyclocondensation reaction. 27412-71-1 belongs to class pyrazoles-derivatives, name is 5-Phenyl-1H-pyrazol-3(2H)-one, and the molecular formula is C9H8N2O, Safety of 5-Phenyl-1H-pyrazol-3(2H)-one.

Elfahham, H. A. published the artcileSynthesis of heterocycles through the reactions of nitrilimines with amino and oxo diazoles, Safety of 5-Phenyl-1H-pyrazol-3(2H)-one, the main research area is pyrazoletriazole; pyrazolopyrazine; pyrazoloimidazole; nitrilimine cyclocondensation diazole; pyrazole amino hydroxy cyclocondensation nitrilimine.

Fused azoles such as pyrazolo[5,1-c][1,2,4]triazoles, pyrazolo[3,4-b]pyrazine and pyrazolo[1,5-a]imidazole have been prepared from the reactions of nitrilimines , produced from hydrazidoyl halides I (R = Cl, Me, MeO), or II (R1 = NO2, Me), with amino- and oxo-azoles. In some cases acyclic products are formed.
