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.
