Zinc acetylacetonate (Zn(acac)2) is a catalyst for the coupling of aryl substituted allylic alcohols with β-dicarbonyl compounds,1 and of organoboranes with organohalides; selective C-alkylation of β-diketones; preparation of amino acid derivatives, aminomaleimides, and β- trichloromethyleneamino diones. Zn(acac)2 is a widely available catalyst which is prepared through the reaction of ZnSO4, acetylacetone and NaOH, to give either the hydrate or the anhydrous zinc complex.5 Zn(acac)2 can perform two general types of reactions: (1) stoichiometric reaction at the nucleophilic carbon of the zinc acetylacetonate, and (2) catalytic reaction at the nucleophilic carbon of other β-dicarbonyl substrates.
