| 摘 要： | 钯催化的Ullmann反应合成C-N键获得成功~(1-3]),在各种配体参与下廉价的铜催化Ullmann反应形成C-N键,引起了人们的关注~(4-5]).配体在活化铜催化的偶联反应中非常关键,就此类催化体系所选的配体而言,目前报道的主要有N,N配体(如1,10-邻菲咯啉~(6])和二胺~(7])等)、N,-COOH配体(如氨基酸~(4]))、O,O配体(如联萘二酚~(8])和1,3-二酮~(9]))、N,P配体~(10-11])等,作者也曾用空气稳定的三价膦配体促进了此类反应~(12]).

| Abstract: | A general,efficient and inexpensive catalyst system for the coupling reaction of aryl iodides and arylamines was studied in this paper.By using 10 mol%of Cu_2O as the copper source,15 mol%of dimethylglyoxime as the ligand,K_3PO_4·3 H_2O as the base,and DMF as the solvent,a series of diarylamines were synthesized with moderate yields. |
