Abstract:

A new H8-BINOL polymer was synthesized by radical polymerization and proved to be an effective catalyst in enantioselective addition of triethylaluminium to aromatic aldehydes in the presence of titanium isopropoxide. The polymer can be prepared with simple steps and reused without losing its enantioselectivity and catalytic activity.

Key words: H8-BINOL, Radical polymerization, Triethylaluminium, Asymmetric addition, Enantioselectivity
