ABSTRACT:
The present invention provides an improved, economical and environmentally benign process for metal complexes of acetylacetone having the general formula, M(acac)nwherein M is a metal cation selected from the group consisting of Fe, Co, Ni, Cu, Zn, Al, Ca, Mg, Mo, Ru, Re, U, Th, Ce, Na, K, Rb, Cs, V, Cr, and Mn etc., n is an integer which corresponds to the electrovalence of M, are obtained by reacting the corresponding metal hydroxide, metal hydrated oxide or metal oxide with a stoichiometric amount of acetylacetone and separating the product.
