A novel copper-catalyzed chemoselective oxidative O-aroylation of 2-acetylphenols, alkyl salicylates and 1,3-dicarbonyl compounds with a wide range of styrene derivatives are described. This approach provides an efficient chemoselective preparation of phenol, alkyl salicylate and enol esters in good to excellent yields. This method represents an alternative protocol for the classical esterification reactions.

We describe the chemoselective conversion of carboxylic acids to functional aromatic ketones promoted by a tailored organophosphate ester in the presence of a Br?nsted acid. The protonated phosphate ester reacts with the carboxylic acid to form acyl phosphate, which reacts with benzenes to give aromatic ketones, probably through the acylium ion or its equivalent. The reaction time is short even at room temperature, and the reaction is compatible with various other functional groups, including amines, olefins, esters, amides and nitriles.

A copper-catalyzed oxidative esterification of 2-carbonyl substituted phenols from the alcohol oxidation level is described. This protocol represents direct access to a range of 2-carbonylated aryl benzoate derivatives, which are important building blocks in the synthesis of natural and pharmacological compounds.
