Popis: | A series of new pyrazolone and pyrazole derivatives with expected antifungicidal activity have been prepared through the reactions 3-phenyl-1-H-pyrazol-5(4H)-one (3) and 4-(dimethylaminomethylene)-3-phenyl-1H-pyrazol-5(4H)-one (5) with a variety of electrophilic reagents and nucleophilic reagents. The newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR and mass spectral studies. |
