Synthesis and Characterization of (+)-α-Phenylethanammonium Phosphotungstate and Its Catalytic Performance for Asymmetric Epoxidation

Abstract

Abstract: A new inorganic-organic hybrid polyoxotungstate with optical activity, (+)- α-phenylethanammonium phosphotungstate (C8H12-N)3PW12O4 0, was synthesized by a mild hydrothermal technique, and its structure was cha racterized by various methods. The catalyst showed good activity for the epoxidation of α-phenylethanammonium-cis-1-propenylphosphonate into α-phenylethanammonium-cis-1,2-epoxypropyl phosphotate.

Key words: hydrothermal synthesis, (+)-&alpha, -phenylethanammonium phosphotungstate, &alpha, -phenylethanammonium-cis-1-propenylphosphonate, asymmetric epoxidation
