ABSTRACT OF THE DISCLOSURE: A process for the preparation of cobalt (III) acetyl- acetonate by oxidation of cobalt (II) acetylacetonate by means of hydrogen peroxide in the presence of the stoichiometrically required amount of acetylacetone in an organic solvent, wherein the organic solvent used is a solvent that is miscible with water and inert to hydrogen peroxide, and in which the cobalt (II) acetylacetonate was prepared and is present in solution. This process is particularly interesting in that it does not require the use of isolated cobalt (II) acetylacetonate as starting material and it give yields of over 95%.
