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 ...

The influence of surfactants on acylation in anhydrous hydrogen fluoride

Journal of Fluorine Chemistry, 1992
Abstract We investigated the acylation reaction of aromatic compounds with anhydrides, acids and acid halides in the presence of anhydrous hydrofluoric acid (AHF) and anhydrous hydrofluoric acid/surfactant mixtures as catalysts. Simons et al. [Simons et al., J. Am. Chem.

A new method for eliminating carbonyl fluoride from α-trifluoromethylated acyl fluorides

Journal of Fluorine Chemistry, 1982
Abstract 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, 2020
Abstract Decarbonylative cyanation of acyl fluorides can be catalyzed by a Pd/Xantphos system. This protocol is also applicable to the conversion of acyl chlorides.

Reactions of group IVB compounds with acyl fluorides

Journal of Organometallic Chemistry, 1971
Abstract Derivatives of acyl fluorides can be readily prepared in high yields by reaction with Group IVB compounds. The reaction may be represented as where n =0-3, and, when M is Si, Y may be nitrogen, oxygen, sulfur, or halogen. When M is Ge or Sn the scope of the reaction is more limited, but oxygen and nitrogen derivatives may be prepared ...

Oxidation of primary alcohols to acyl fluorides using BrF3

Journal of Fluorine Chemistry, 1996
Abstract Aliphatic and alicyclic primary alcohols when treated with BrF 3 were rapidly oxidized to the corresponding acyl fluorides. The reaction is of an ionic nature. The main by-product was found to be the symmetrical ester which originates from the reaction between the acyl fluoride and unreacted starting alcohol.

Electronic Spectra of Isoelectronic Amides, Acids, and Acyl Fluorides

The Journal of Chemical Physics, 1968
The first four bands in the gas-phase spectra of amides, carboxylic acids, and acyl fluorides are thought to be n → π*, n → 3s Rydberg, π → π*, and n → 3p Rydberg excitations. That the second and fourth bands are Rydberg, whereas the first and third are valence shell is demonstrated in a comparison of gas-phase and condensed-phase absorption and ...
