A versatile and highly efficient method for the direct synthesis of α-keto esters and 1,2-diketones utilizes an oxidative cleavage of various β-keto esters and 1,3-diketones by an Oxone/aluminum trichloride system. The simple, environmentally benign one-step oxidation reaction proceeded selectively in aqueous media to afford products in high yields and short reaction times.
