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.

Alumina-accelerated methanolysis and hydrolysis of acyl and phosphoryl fluorides
Journal of Fluorine Chemistry, 1981Abstract We have discovered that Woelm chromatographic γ-alumina substantially accelerates hydrolysis (and methanolysis) of acyl and phosphoryl fluorides. Compared to the corresponding homogeneous reactions, these heterogeneous alumina-promoted reactions occur about 250–350 times faster for acyl fluorides and about 1800–3000 times faster ...

Reactions of group IVB compounds with acyl fluorides
Journal of Organometallic Chemistry, 1971Abstract 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, 1996Abstract 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, 1968The 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 ...

Acid Fluorides as Acyl Electrophiles in Suzuki–Miyaura Coupling
European Journal of Organic Chemistry, 2017The first palladium‐catalyzed construction of ketones through Suzuki–Miyaura reaction by using acid fluorides is described. In contrast to typical acyl electrophiles such as acid chlorides, acid fluorides are uncommon acyl electrophiles to use in boron‐based coupling reactions, probably due to a high level of stability toward nucleophiles.

Facile conversion of perfluoroacyl fluorides into other acyl halides
Journal of the Chemical Society, Perkin Transactions 1, 1996Nine perfluoroacyl fluorides underwent halogen exchange when treated with anhydrous lithium halides to give acyl chlorides, bromides and iodides in high yields. The temperature dependence of this reaction is described. In the reaction with perfluorodiacyl fluoride, the diacyl halides possessing different acyl halide-groups were also produced.

Asian Journal of Organic Chemistry
AbstractAcyl fluorides, carbamoyl fluorides and fluoroformates have been employed as efficient reagents in a number of organic syntheses. Their application in catalytic transformations, however, began to be explored in the early 2000s. Recently, these reagents have increasingly gained attention owing to their unique reactivity in diverse catalytic ...
