An effective process for the conversion of carboxylic acid to ketone has been discovered. In this process, carboxylic acid has been activatedusing p-toluene sulphonyl group. Under the optimized condition, aromatic, aliphatic heteroaromatic carboxylic acids have been proved to be good substrates for this methodology. The byproduct of this reaction can be removed very easily during work up process.

tautomerisation and hydrolysis gave α-hydroxy ketones, ketones, and γ-keto esters in good yield, thereby providing a convenient new acyl-anionequivalent. Reaction of these lithium salts with aldehydes and ketones, followed by elimination provided a new route to azo alkenes.
