2-chloro-4,5-difluorobenzoyl fluoride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Into a 200 cc glass reactor equipped with a reflux condenser, 50 g of 2-chloro-4,5-difluorobenzoylchloride, 13.7 g of spray dried potassium fluoride and 100 g of sulforane were charged and reacted at 135° C. for 4 hours under stirring. After cooling, the inorganic salts were filtered off, and the residue was subjected to distillation under reduced pressure to obtain 42 g of 2-chloro-4,5-difluorobenzoyl fluoride. The physical properties of the obtained 2-choloro-4,5-difluorobenzoyl fluoride were as follows.
