Acetylacetonate (acac) complexes of titanium and zirconiumwere examined for their reactivity with alcohols and diols.Alcoholysis of the acac ligand resulted in the formation ofacetone and the acetyl ester of the alcohol, with the concomitantformation of the metal alkoxide. The Zr(acac)4complex was more reactive than theTi(acac)2(OR)2 complexes (OR =alkoxide) while the reactivity of the alcohols increase in the ordertertiary < secondary ≪primary.
