nitrogenation suffered from simple amidation/amination with limited atom‐economy and is mostly limited to C(sp2)−H substrates. In this work, anthranil was designed as a novel bifunctional aminating reagent for both C(sp2)−H and C(sp3)−H bonds under rhodium(III) catalysis, thus affording a nucleophilic aniline tethered to an electrophilic carbonyl. A tridendate rhodium(III) complex has been isolated as the
以前的直接CH H氮化反应受简单的酰胺化/胺化作用和原子经济的限制,并且大多限于C(sp 2)-H底物。在这项工作中,将蒽醌设计为在铑(III)催化下同时用于C(sp 2)-H和C(sp 3)-H键的新型双功能胺化试剂,从而提供了拴接到亲电羰基的亲核苯胺。已经分离出三登酸盐铑(III)配合物作为催化剂的静止状态,DFT研究确定了亚硝基物质的中间体。
