Asymmetric Catalysis for Oxidative Coupling of 2-Naphthol to BINOL 

Catalyst ligand Temperature Time Solvent Conversion Selectivity Ee% 

The chiral self-dimerization oftheV complex precursors at the Si02 surface produced a unique reaction space for the selective oxidation. 

Notably, even if the V monomer precursors (1) are racemic at the V center in solution, only a particular arrangement of two V monomers among possible structural arrangements is allowed as a stable structure at the Si02 surface, creating a new chiral V center (2) to provide a chiral reaction space for the enantioselective catalysis. Chiral self-assembly is a common phenomenon that is applied to other catalytic materials on surfaces.
