    • An aromatic compound represented by the general formula Ar1X is reacted with a palladium compound and a phosphine derivative, in the presence of a first basic substance, thereby producing a palladium-complex compound represented by the general formula Ar1—PdL2X. This palladium-complex compound is reacted with a benzoic acid represented by the general formula Ar2—COOH, in the presence of a second basic substance, thereby producing another palladium-complex compound represented by the following general formula. The above palladium-complex compounds are useful as catalysts and can be produced easily by the above reactions. In the above general formulas, Ar1 is an aryl group; and X is a halogen that is fluorine, chlorine, bromine or iodine, trifluoromethanesulfonate group, an alkylsulfonate group having a carbon atom number of 1-4, or a substituted or unsubstituted arylsulfonate group; each L is independently a phosphine ligand; and Ar2 is an aryl group.
    • 在通式Ar 1 X表示的芳香族化合物与钯化合物和膦衍生物在第一碱性物质的存在下反应,由此制备由通式Ar 1〜 PdL2X。 在第二碱性物质的存在下,使该钯络合物与通式为Ar 2 -COOH表示的苯甲酸反应,由此生成由以下通式表示的另一种钯络合物。 复合化合物可用作催化剂,并且可以通过上述反应容易地制备。 在上述通式中,Ar 1是芳基; X是氟,氯,溴或碘的卤素,三氟甲磺酸酯基,碳原子数为1-4的烷基磺酸酯基或取代或未取代的芳基磺酸酯基; 每个L独立地是膦配体; Ar 2为芳基。
