| 摘 要： | A series of Pd(Ⅱ)-enaminone complexes,termed Pd(eao)2,have been synthesized and characterized.The investigation on the catalytic activities of these new Pd(Ⅱ)-reagents has proved that the Pd(ea0)2-1 possesses excellent catalytic activity for the Suzuki-Miyaura cross coupling reactions of aryl bromides/chlorides with ary/vinyl boronic acids in the environmentally benign media of aqueous PEG400 at low loading(5 mol‰).The superiority of this Pd(Ⅱ)-reagent to those commercial Pd(Ⅱ)and Pd(0)catalysts in catalyzing the reactions has been confirmed by parallel experiments.What's more,Pd(eao)2-2 has been found as a practical catalyst for the homo-coupling reactions of aryl boronic acids.

| Abstract: | A series of Pd(II)‐enaminone complexes, termed Pd(eao)2, have been synthesized and characterized. The investigation on the catalytic activities of these new Pd(II)‐reagents has proved that the Pd(eao)2‐ 1 possesses excellent catalytic activity for the Suzuki‐ Miyaura cross coupling reactions of aryl bromides/chlorides with aryl/vinyl boronic acids in the environmentally benign media of aqueous PEG400 at low loading (5 mol‰). The superiority of this Pd(II)‐reagent to those commercial Pd(II) and Pd(0) catalysts in catalyzing the reactions has been confirmed by parallel experiments. What's more, Pd(eao)2‐ 2 has been found as a practical catalyst for the homo‐coupling reactions of aryl boronic acids. |
