The Baeyer–Villiger Oxidation of Ketones Catalyzed by Nickel(II) Complexes with Combined Use of Molecular Oxygen and an Aldehyde

Abstract In the presence of a catalytic amount of a nickel(II) complex coordinated with 1,3-diketone, various cyclic or acyclic ketones are converted into the corresponding lactones or esters by the Baeyer–Villiger oxidation on treatment with an atmospheric pressure of molecular oxygen (oxidant) and an aldehyde (reductant) at room temperature.
