Synthesis, 2022
Studies on the activation of carbon–fluorine bonds have been reported intensively in recent years. Among them, acyl fluorides have been utilized as versatile reagents for acylation, arylation, and even fluorination.

Nickel/copper-cocatalyzed decarbonylative silylation of acyl fluorides
Chemical Communications, 2019A transformation of acyl fluorides with silylboronvianickel/copper-cocatalysed carbon–fluorine bond cleavage and a sequential decarbonylation, which provides an efficient protocol to functionalize arylsilanes, has been disclosed.

Preparations and reactions of acylated and partially acylated glycosyl fluorides
Carbohydrate Research, 1993Abstract Partial acylation of glycosyl fluorides in the galacto (2 and 3) and gluco series (8–10) is readily achieved. Attempts to further alkylate these acyl derivatives failed. Treatment of 2 with Lewis acid, however, provided a facile route to the 1,4-anhydro derivative 5 . Lewis acid-mediated glycosylation of 2-acetamido-3,4,6-tri- O -

Nickel-Catalyzed Decarbonylative Thioetherification of Acyl Fluorides via C–F Bond Activation
Synthesis, 2021Nickel-catalyzed decarbonylative thioetherification of acyl fluorides has been developed. This transformation allows an array of acyl fluorides to react with thiophenols. A wide range of functional groups are well tolerated and the corresponding sulfides

Tetramethylammonium trifluoromethylthiolate, [N(CH3)4]SCF3, is a mouthful to say, but the inexpensive, bench-stable, and easy-to-use salt has been impressing chemists over the past few years for its versatility in adding SCF3 groups to molecules and as a fluorinating reagent.

Organic Letters, 2021
In this Letter, the palladium/copper-cocatalyzed arylsilylation of internal alkynes with acyl fluorides and silylboranes is described. This is the first example in which acyl fluorides have been utilized for the three-component coupling reaction via ...
