Alumina-accelerated methanolysis and hydrolysis of acyl and phosphoryl fluorides

Journal of Fluorine Chemistry, 1981
Abstract 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 ...

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.

Catalytic Synthesis of Carbonyl Compounds Using Acyl Fluorides, Carbamoyl Fluorides, and Fluoroformates: An Overview

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 ...
