Aromatic 1,3-diketones are produced by reacting aromatic compounds with acetoacetyl fluoride optionally substituted in .gamma.-position by fluorine, chlorine and/or bromine, in hydrofluoric acid of at least 90% strength at a temperature of from about -40 to +50.degree.C. The products obtained are important starting products and intermediates for the manufacture of dyestuffs, plastics and pharmaceuticals. Furthermore they can be used for the formation of metal complexes and metal extracting agents, solution intermediaries and solvents.
芳香族1,3-二酮是通过将芳香族化合物与在γ位上选择性取代氟、氯和/或溴的乙酰乙酰氟反应,在至少90%强度的氢氟酸中,在约-40至+50℃的温度下制得。所得产品是制造染料、塑料和药品的重要起始产品和中间体。此外,它们还可用于形成金属络合物和金属萃取剂、溶液中间体和溶剂。
