Herein, we report the natural ligand quebrachitol (QCT) as a promoter for a Cu(II) catalyst, which is highly effective for N-arylation of various amines and related aryl halides. A series of diarylamine derivatives were obtained in high yields by using diethylene glycol (DEG) as both ligand and solvent. The C–N coupling reactions proceed under mild conditions and exhibit good functional group tolerance
在本文中,我们报告了天然配体 quebrachitol (QCT) 作为 Cu(II) 催化剂的促进剂,它对各种胺和相关芳基卤化物的 N-芳基化非常有效。通过使用二甘醇(DEG)作为配体和溶剂,以高收率获得了一系列二芳胺衍生物。C-N偶联反应在温和的条件下进行并表现出良好的官能团耐受性。
