Procedure

2,3-Dichloro4-trifluoromethoxybenzoyl chloride (17.2 g) was added to a mixture of antimony trifluoride (10.6 g) and antimony pentachloride (1 g). The mixture was heated at reflux for 10 mins then flash distilled to give crude 2,3-dichloro-4-trifluoromethoxybenzoyl fluoride (20 g) as a semi-solid bp 211°-215° C.
