반응 단계

A sealed glass tube containing 36.2 g of bis(trifluoromethyl)diazomethane and 10.2 g of cyanoacetylene was heated at 50°C for 24 hours. The product was distilled to give 40.1 g of 3,3-bis(trifluoromethyl)-5-cyano-3H-pyrazole, bp 38°C/12 mm. The ultraviolet, infrared, and mass spectra as well as the proton and fluorine nuclear magnetic resonance spectra were consistent with the proposed structure.
