Development of an efficient method for the preparation of functionalized nano-particles

Abstract

Immobilization of asymmetric catalysts has been achieved utilizing the spherical nano-particles that function like dendrimer. Asymmetric catalysts such as Al-Li-bis(binaphthoxide), Ga-Na-bis(binaphthoxide) and μ-oxodititanium complexes were successfully introduced on the surface of either micelle-derived polymer (MDP) or monolayer-protected metal cluster (MPC). In addition, utilizing metal-bridged polymers, a simple and efficient method for the immobilization of catalyst without the need for a polymer support has also been realized. The Immobilized catalysts thus obtained displayed high activity affording the corresponding products with high enantiomeric excesses.
