Abstract
2,6-Difluorobenzoicnitrile was synthesized by 2,6-dicholobenzomitrile and high activity anhydrous potassium fluoride using tetramethylene sulfone as solvent.The yield was 87.6%.2,6-Difluorobenzamide and 2,6-difluorobenzoic acid were synthesized from 2,6-dicholobenzomitrile by the hydrolysis in analkaline solution.The yield was 89%,90.5%,respectively.
