Decarboxylative Cross-Coupling of Acyl Fluorides with Potassium Perfluorobenzoates
Organic Letters, 2020We report the transition metal-free decarboxylative cross-coupling reactions of acyl fluorides with potassium perfluorobenzoates. Compared with traditional transition metal-catalyzed cross-couplings, this protocol presents an extremely environmentally benign pathway to afford unsymmetrical diaryl ketones.

Copper‐Catalyzed Asymmetric Acylboration of 1,3‐Butadienylboronate with Acyl Fluorides
Angewandte Chemie International Edition, 2023AbstractWe report herein a Cu‐catalyzed regio‐, diastereo‐ and enantioselective acylboration of 1,3‐butadienylboronate with acyl fluorides. Under the developed conditions, the reactions provide (Z)‐β,γ‐unsaturated ketones bearing an α‐tertiary stereocenter with high Z‐selectivity and excellent enantioselectivities.

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 -

Recent Advances in the Synthesis of Acyl Fluorides
Synthesis, 2020AbstractAcyl fluorides are valuable intermediates in organic synthesis. They are increasingly employed in peptide synthesis, in challenging esterification and amidation reactions or in transition-metal-catalyzed transformations. This review summarizes recent advances in their preparation.1 Introduction2 Nucleophilic Fluorination2.1 α-Fluoroamine ...

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.

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.
