Direct Access to Acyl Fluorides from Carboxylic Acids Using a Phosphine/Fluoride Deoxyfluorination Reagent System

Organic Letters, 2019
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.

1,2-Acylcyanation of Styrenes by Photoinduced Nickel Catalysis to Generate Acyl Radicals from Acyl Fluorides

Organic Letters
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.
