rhodium(III) (CpRhIII) complexes are powerful catalysts for promoting asymmetric C−H activation reactions. At present, their preparations mainly rely on the development of various chiral cyclopentadienyl (Cp) ligands by linking or embedding the Cp motif to or into a certain chiral backbone. In contrast, development of planar-chiral only CpRhIII catalysts bearing non-chiral Cp ligands remains a formidable
