Bioinspired pentadentate ligand N‐confused porphyrin (NCP) bearing a 2‐mercaptopyridine group and its Ru^II and Co^III complexes were synthesized. Their structures were revealed by single‐crystal X‐ray crystallographic analysis. Installation of an axial thiopyridine ligand shifts the redox potentials negatively and enhances the catalytic activity largely, which was demonstrated in the cyclopropanation reaction using the Co complex.

N-混淆的卟啉金属配合物，其内部碳原子直接束缚有轴向吡啶：一种生物启发的配体，作为多功能的催化平台

合成了带有2-巯基吡啶基团的受生物启发的五齿配体N-混淆卟啉（NCP）及其Ru ^II和Co ^III复合物。通过单晶X射线晶体学分析揭示了它们的结构。轴向硫代吡啶配体的安装使氧化还原电势发生负向移动并大大增强了催化活性，这在使用Co配合物的环丙烷化反应中得到了证明。
