Several α,α-difluoroarylacetic acids have been prepared by reaction of DAST ((diethylamino)sulfur trifluoride) with esters of α-oxoarylacetic acids and then hydrolysis of the resulting difluoro ester.Examples include the α,α-difluoro derivates of the synthetic plant auxin, α-naphthylacetic acid, and the antiinflammatory drug, ibufenac.
