A fast and simple method for deoxyfluorination of carboxylic acids is presented. The protocol employs commodity chemicals (PPh3, NBS, fluoride), affording products in excellent yields under mild conditions. Acyloxyphosphonium ion, the key reaction intermediate, was identified by NMR spectroscopic methods.

A new method for eliminating carbonyl fluoride from α-trifluoromethylated acyl fluorides
Journal of Fluorine Chemistry, 1982Abstract Carbonyl fluoride was found to be eliminated from α-trifluoromethylated acyl fluorides when they are treated with amides, e g. , dimethylformamide, dimethylacetamide, and dimethylthioamide, under mild condition, e.g. , Possible reaction mechanism will be discussed.

Palladium-catalyzed Decarbonylative Cyanation of Acyl Fluorides and Chlorides
Chemistry Letters, 2020Abstract Decarbonylative cyanation of acyl fluorides can be catalyzed by a Pd/Xantphos system. This protocol is also applicable to the conversion of acyl chlorides.

1.1 Sulfonyl Fluorides and Acyl Fluorides
AbstractSulfonyl fluorides have numerous applications in both synthetic organic chemistry as fluorinating agents and as precursors to sulfur(VI) moieties, and in chemical biology as covalent inhibitors and chemical probes. The utility of sulfonyl fluorides arises from the properties of the S—F bond, as the high bond strength and polarization imparts ...J. Lai, B. J. Thomson, G. M. Sammis
