2,4-Difluorobenzonitrile Chemical Properties, Uses, Production

Chemical Properties

white crystalline solid

Uses

2,4-Difluorobenzonitrile has been used in the synthesis of:

  • 2-methylsulfonyl-4-fluorobenzylamine
  • fluoro-3-amino-1,2-benzisoxazoles

General Description

2,4-Difluorobenzonitrile undergoes polycondensation with Bisphenol A and matrix-assisted laser desorption/time-of-flight mass spectra revealed a quantitative formation of cyclic oligoethers and polyethers.

Synthesis

2,4-DIFLUOROBENZAMIDE

2,4-Difluorobenzonitrile

3939-09-1

General procedure for the synthesis of 2,4-difluorobenzonitrile from 2,4-difluorobenzamide: In a 250 mL three-necked flask, 2,4-difluorobenzamide (23.0 g, 146.2 mmol) was dissolved in dry N,N-dimethylformamide (80 mL), and cooled to -15°C. The reaction was continued for 0.5 h at room temperature. Phosphorus oxychloride (112.1 g, 730.9 mmol) was slowly added dropwise and the reaction was kept for 0.5 h. The reaction was then continued for 7 h at room temperature. Upon completion of the reaction, the reaction solution was slowly poured into a vessel containing ice to induce precipitation of solids. Finally, 17.0 g of 2,4-difluorobenzonitrile was obtained in 83.4% yield.
