چکیده انگلیسی
The synthesis of 4,4′-arylmethylene-bis(3-(trifluoromethyl)-1-phenyl-1H-pyrazol-5-ol) was performed effectively in aqueous media without catalyst by the reaction of aryl aldehydes and 1-phenyl-3-trifluoromethylpyrazol-5-one. All of the compounds obtained were characterized by elemental analysis, FTIR and 1H NMR. The structure of compound 3g was further confirmed by the X-ray single crystal diffraction. The method has the advantages of mild condition, without any catalyst, high yields and environmentally benign procedure.
The synthesis was performed in aqueous media without any catalyst. Figure optionsDownload as PowerPoint slide
