diarylamines efficiently produced from arylamines and p-nitrosoanisole derivatives by intermolecular SNAr under weak acid conditions. Relying on the catalysis of hydrogen protons, the SNAr reaction, which is endowed with resistance to space crowding, tolerance to halogen and nitroso groups, and high regioselectivity, can be carried out under mild conditions, even if the substrates involved do not have strong
弱酸条件下,芳胺与对亚硝基苯甲醚衍生物通过分子间 S N Ar 高效生成多官能团二芳胺。 S N Ar反应依靠氢质子的催化作用,具有抗空间拥挤性、对卤素和亚硝基的耐受性以及高区域选择性,即使所涉及的底物不存在,也可以在温和的条件下进行。强吸电子基团。
