The catalytic activity of Cu β-diketonates, e.g. copper acetylacetonate [13395-16-9], in the formation of urethanes was determined by several factors. This was due to the change of effective changes on the Cu and O atoms of the chelate bond, depending on the influence of ligand substituents on π-factors of the Cu-ligand bond. These changes in electron structure of the catalyst in turn influenced the electron structure of the reagents, isocyanate and alc. This influence led to a change both in electron d. of the alc. O and in OH-bond length thus producing a change in orientation of the alc. mol. in regard to the isocyanate.
