ring-opening oxidative sulfonylation to afford γ-keto sulfones when reacting with sulfinate salts in the presence of copper(II) acetate catalyst and an oxidant (tert-butyl hydroperoxide or atmospheric oxygen). Various fluroalkyl, aryl and alkyl sulfinate salts are successfully employed as sulfonylation reagents, affording the corresponding sulfones up to 94% yields. The experimental protocol is mild
