Enantioselective Alcoholysis

A Rh-catalyzed enantioselective intermolecular dehydrogenative Si−O coupling of dihydrosilanes with alocohols and silanols is demonstrated. Rh(I) catalyst equipped with a Josiphos ligand enables the highly enantioselective alcoholysis process of dihydrosilanes, giving access to a variety of functionalized triorgano-substituted silicon-stereogenic alkoxysilanes and siloxanes in decent yields and ee, which significantly expand the chemical space of the silicon-centered chiral molecules. Utility of this methodology is illustrated by the construction of CPL-active (circularly polarized luminescence) chiral alkoxysilane small organic molecules.

Luminescence Behavior

Optically active poly(thioether) are obtained based on CPL-triggered thiol–ene photopolymerization assisted with achiral HAD. The poly(thioether) exhibits clusterization-triggered emission and circularly polarized luminescence behavior.
