| Tikrit Journal of Pure Science | ||
| Article 1, Volume 21, Issue 7, 2016, Pages 86-94 | ||
| Abstract | ||
| This research included the preparation of new pyrazole derivatives from the condensation of the benzoyl acetone with carboxylic acid hydrazide in ethanol as a solvent. The reaction included two steps from the tetra surfaces nucleophilic addition and cyclisation process in second step. The pyrazole derivatives products were reacted with Diazonium salts. The prepared compounds were characterized by infrared, Nuclear Magnatic resonance spectroscopy and the completing of the reaction was checking by the TLC. | ||
