Aluminum(III) Chloride → 2,4-Difluorobenzoyl chloride

Participants

Reaction Conditions

Reaction Steps

13.5 g (.085 mol) of 2,4-diflurobenzoylfluoride were cooled to about 5° C. Aluminum chloride (3.7 g; 0.028 mol) was added slowly over about 0.5 hour. The conversion to the aroyl chloride was 80% (as determined by Gas Chromatography). The reaction was warmed to 90° C. Complete conversion of the starting material resulted. The product was distilled at reduced pressure to yield 2,4-difluorobenzoylchloride as a colorless liquid. This material was not assayed but used directly in the reduction step.
