铼催化的醇脱羟基反应研究进展

Recent Progress in Re-Catalyzed Dehydroxylation Reactions

近年来,发展将丰富的可再生资源转化成燃料和高附加值化学品的新型高效方法引起人们的广泛关注.其中的研究热点之一是多元醇和碳水化合物的选择性化学转换.多元醇及碳水化合物富含氧元素,其很大部分是以羟基官能团的形式存在,因此发展选择性的脱羟基反应具有重要的意义.介绍了近年来铼催化的醇脱羟基反应的研究进展,主要分为两部分:(1)单醇的脱羟基反应构建新的化学键;(2)二(多元)醇的脱羟基反应生成烯烃.

The development of novel effective processes for the conversion of abundant renewable resources to fuels and value-added chemicals has spurred new interest in the discovery of selective chemical transformations of polyols and carbohydrates. These compounds have high oxygen content, which is mostly present in the form of hydroxyl groups. Therefore, partial or complete removal of the hydroxyl groups is of great importance. Herein a brief overview on the development of rhenium-catalyzed dehydroxylation reactions in recent years is given, which are roughly classified into two categories：（1） dehydroxylation reactions of monools for new chemical bond formation and（2） dehydroxylation reactions of diols and polyols for olefin syntheses.
