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.

Abstract Reactive acyl trifluoromethanesulfonates are formed from the reaction of acyl fluorides with trimethylsilyl trifluoromethanesulfonate (TMSOTf). These electrophiles undergo Friedel–Crafts reactions with electron-rich aromatics at room temperature. When a sulfur atom is present at their γ position, their cyclization to acylsulfonium cations is

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 ...

Facile Formation of N-Acyl-oxazolidinone Derivatives Using Acid Fluorides
Organic Letters, 2010A mild method is presented for the formation of N-acylated oxazolidinones that employs acid fluorides and mild bases, such as (i)Pr(2)NEt and NEt(3). Optimized reaction conditions for two types of substrates have been developed utilizing either the oxazolidinone itself or the corresponding in situ generated O-silyloxazolidinones resulting in the ...

Catalytic C−H/C−F Coupling of Azoles and Acyl Fluorides
Chemistry – A European Journal, 2019AbstractA method for the palladium/copper‐catalyzed direct acylation of azoles with acyl fluorides is described. This study reports the first examples of acyl fluorides being used as acylation reagents in transition‐metal‐catalyzed aromatic C−H bond functionalization reactions.

We report herein a photoinduced nickel-catalyzed 1,2-acylcyanation of styrenes with acyl fluorides and trimethylsilyl cyanide (TMSCN). Nickel(II) acyl complexes, formed from nickel(0) complexes and acyl fluorides, are photoexcited to generate acyl radicals via a ligand-to-metal charge transfer (LMCT) process.
