Intermolecular aromatic C(sp2)–H amination promoted by neutral rhodium nitrenoids has been developed. The reactions proceeded with various oxygen-substituted arenes (1.5 equiv.) in a chemo- and regioselective manner. The aromatic C(sp2)–H amination took place at the para position of the oxygen substituent in the presence of benzylic C(sp3)–H bonds and/or C(sp3)–H bonds α to ethereal oxygen.
已开发出由中性铑亚硝烯类化合物促进的分子间芳族C(sp 2)–H胺化反应。反应以化学和区域选择性方式与各种氧取代的芳烃(1.5当量)进行。在存在苄基C(sp 3)-H键和/或C(sp 3)-H键与醚氧结合的情况下,芳族碳(sp 2)-H氨基化反应发生在氧取代基的对位。
