An electrochemical On-Off method for phenolic ester synthesis from N-alkoxyamides has been reported. This one-pot protocol begins with rapid and selective electrodimerization of the amide using n-Bu4NI (TBAI) as an electrocatalyst. The reaction proceeds further in the absence of current via Zn catalyzed C?N bond activation of the amide dimer followed by its coupling with phenol to form the ester. The present methodology is ligand-free and takes place under mild reaction conditions. This transformation incorporates a wide variety of phenols and amide substrates leading to the formation of functionalized esters highlighting its versatility. (Figure presented.).

The possibility of preparing 4-fluorophenol or 4-fluorobenzoic acid via the Baeyer-Villiger reaction starting from unsymmetrical fluoroaryl ketones is disscussed.Several unsymmetrical 4-fluorobenzophenones having different substituents in the fluorine-free aryl group were prepared and converted to esters by treatment with peracetic acid.The electrophilicity of the substituents influenced the molecular structure of the ester formed as a result of a carbon-to-oxygen migration, and hence 4-fluorophenol or 4-fluorobenzoic acid formation.Electron-withdrawing substituents favoured the formation of 4-fluorophenol in good yields, while electron-donating substituents formed 4-fluorobenzoic acid preferentially.
