1，2-Diphenyl-3，4-bis[(2，4，6-tri-tert-butylphenyl)亚膦]环丁烯作为添加剂配体用于铜催化的卤代苯与胺在碱存在下的胺化反应，以很好到很好的产率得到相应的仲胺或叔胺。
1,2-Diphenyl-3,4-bis[(2,4,6-tri-tert-butylphenyl) phosphinidene] cyclobutene was used as an additive ligand in copper-catalysed amination reactions of halobenzenes with amines in the presence of base to afford the corresponding secondary or tertiary amines in good to excellent yields.
