2-Diphenylphosphino-2′-hydroxy-1,1′-binaphthyl as a chiral auxiliary for asymmetric coordination chemistry

Abstract

In this study, the bidentate ligand (R)-2-diphenylphosphino-2′-hydroxy-1,1′-binaphthyl (HO-MOP) was investigated as a chiral auxiliary for the asymmetric synthesis of ruthenium polypyridyl complexes. It was found that (R)-HO-MOP serves as an effective chiral auxiliary starting from different precursor complexes, most notably using the commercially available half-sandwich complex [Ru(η⁶-C₆H₆)Cl₂]₂.
