An immobilized vanadium-binaphthylbishydroxamic acid complex as a reusable catalyst for the asymmetric epoxidation of allylic alcohols

摘要

An immobilized polymer-supported vanadium-binaphthylbishydroxamic acid (PS-VBHA) has been developed as an efficient, reusable catalyst for the asymmetric epoxidation of allylic alcohols. This PS-VBHA catalyst shows comparable catalytic performance to that of the parent V-BBHA catalyst and can be reused five times without significant loss of enantioselectivity. (C) 2019 Elsevier Ltd.
