Ligand development for rhodium(III)‐catalyzed C−H activation reactions has largely been limited to cyclopentadienyl (Cp) based scaffolds. 2‐Methylquinoline has now been identified as a feasible ligand that can coordinate to the metal center of Cp*RhCl to accelerate the cleavage of the C−H bond of N‐pentafluorophenylbenzamides, providing a new structural lead for ligand design. The compatibility of
铑(III)催化的CH活化反应的
配体形成主要限于基于
环戊二烯基(Cp)的支架。现已确定
2-甲基喹啉是一种可行的
配体,它可以与Cp * RhCl的
金属中心配位,以加速N-
五氟苯基苯甲酰胺的C-H键的裂解,为
配体设计提供了新的结构线索。该反应与仲游离胺和
苯胺的相容性还克服了
