The metal-free oxidation of dialkyl, alkyl aryl, or alkyl heteroaryl ketones or arylalkynes
to the corresponding carboxylic acids is achieved using an oxidative mixture of Oxone
and trifluoroacetic acid. This green method is a simple and mild protocol to obtain
carboxylic derivatives in excellent yields.
