  Synthesis of 3-Cyanopyrazoles from 3-Trifluoromethyl-pyrazoles 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.

  The 1,3-dipolar cycloaddition of diazomethylsulfone anion, generated in situ from α-diazo-β-ketosulfone, with vinyl sulfone proceeds in a regioselective manner to provide sulfonylpyrazoles. Similar reaction of diazomethylphosphonate anion, derived from Bestmann–Ohira reagent, with vinyl sulfone leads to phosphonylpyrazoles. The sulfonyl group of vinyl sulfone undergoes chemoselective elimination in

  transition-metal-free [3 + 2] cycloaddition reaction between nitroolefins and diazoacetonitrile (N2CHCN) is described. This protocol exhibits several merits including simple starting materials, mild reaction conditions, broad substrate scope, good yields, and regioselectivities. The one-pot three-component reaction of nitroolefins with diazoacetonitrile (N2CHCN) and alkyl halides is also developed, thus delivering
