Oxidation of Aldehydes into Carboxylic Acids with Molecular Oxygen Using Nickel(II) Complex Catalyst

Abstract
The oxidation of aldehydes into the corresponding carboxylic acids using a catalytic amount of nickel(II) complex under an oxygen atmosphere at room temperature is described. Bis[1,3-di(p-methoxyphenyl)-1,3-propanedionato]nickel(II)(Ni(dmp)2) behaves as an excellent catalyst for the oxidation of aldehydes to afford the corresponding carboxylic acids in good yields.
