SYNTHESIS OF 3-CYANOPYRAZOLES FROM 3-TRIFLUOROMETHYLPYRAZOLES VIA DIRECT AMMONOLYSIS REACTION

[摘要]：A simple and green method to prepare 3-cyanopyrazoles in aqueous ammonia from easy-obtained 3-trifluoromethyl-pyrazoles was explored. Most substrates got acceptable yields. The hydrogen position of Nl-H on cyanopyrazoles was assigned by X-ray crystal structure analysis.
