Abstract
Abstract In this work, we have successfully synthesized a new family of chiral Schiff base– phosphine ligands derived from chiral binaphthol (BINOL) and chiral primary amine. The controllable synthesis of a novel hexadentate and tetradentate N, O, P ligand that contains both axial and sp 3-central chirality from axial BINOL and sp 3-central primary amine led to the establishment of an efficient multifunctional N, O, P ligand for copper-catalyzed ...
