The dehydrogenative C–N cross‐coupling of unprotected, secondary anilines through ortho‐N‐carbazolation has been achieved using a Ru catalytic system with O2 as the terminal oxidant. The reactions proceed in an intermolecular fashion, selectively in the ortho position. Implications for the field of organic synthesis are discussed.
通过使用O 2作为末端氧化剂的Ru催化体系,可以通过邻N-咔唑化作用使未保护的仲苯胺进行脱氢C-N交叉偶联。反应以分子间方式进行,选择性地在邻位进行。讨论了对有机合成领域的影响。
