A highly selective phosphorus/nitrogen (P,N) ligand-based iridium catalyst system efficiently catalyzes the reaction of arylamines with unprotected amino alcohols, yielding N-arylated aliphatic diamines in yields of up to 93%. The reaction can be performed with a wide variety of branched and linear amino alcohols in combination with various aminopyridines or substituted anilines.
高度选择性的基于磷/氮(P,N)配体的铱催化剂体系可有效催化芳基胺与未保护的氨基醇的反应,从而以高达93%的产率生成N-芳基化脂肪族二胺。该反应可以用多种支链和直链氨基醇与各种氨基吡啶或取代的苯胺结合进行。
