Abstract

A new catalytic transesterification promoted by a tetranuclear zinc cluster was developed. The mild reaction conditions enabled the reactions of various functionalized substrates to proceed in good to high yield. A large-scale reaction under solvent-free conditions proceeded with a low E-factor value (0.66), indicating the high environmental and economical advantage of the present catalysis.

摘要

开发了一种由四核锌簇促进的新型催化酯交换反应。温和的反应条件使各种功能化底物的反应能够以良好至高收率进行。在无溶剂条件下的大规模反应以低E-因子值（0.66）进行，表明本催化具有很高的环境和经济优势。
