摘要
The [Pd{C6H2(CH2CH2NH2)-(OMe)(2),3,4} (mu-Br)](2) complex of homoveratrylamine was synthesized and its application in the Heck coupling reaction was studied. This complex had been demonstrated to be active and efficient catalyst for the Heck reaction of aryl iodides, bromides and even chlorides. The cross-coupled products were produced in excellent yields in a short reaction time using catalytic amounts of [Pd{C6H2(CH2CH2NH2)-(OMe)(2),3,4} (mu-Br)](2) complex in N-methyl-2-pyrrolidinone (NMP at 130 degrees C).
