Synthesis, spectroscopy, and structures of chiral rhodium(I) corrole complexes

The easily accessible chiral corrole 1 was metallated by rhodium and isolated with additional ligands of very different electronic and steric properties: two carbonyls, a cyclic diphosphine, and a diene. The diamagnetic rhodium(I) complexes were characterized by multinuclear NMR methods and X-ray crystallography. The diphosphine-coordinated complex 2b was obtained non-racemic, which was further confirmed by circular dichroism.
