ABSTRACT:
Process for preparing cobalt(III)acetylacetonate comprising the steps of adding to cobalt(II)acetylacetonate in an organic solvent, at least the stoichiometric amount of acetylacetone, oxidizing with an excess of hydrogen peroxide, and separating the obtained cobalt(III)acetylacetonate by cooling and or concentration of the solution. The product obtained after drying is analytically pure and may be directly used as a catalyst for many chemical reactions, such as dimerizations, oligomerizations and polymerizations, oxidations and hydrogenations of olefins and many more.
