The Summary of main observation and conclusion 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 parts per thousand). 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.
