Abstract

A new method for the catalytic didehydroxylation of vicinal diols is described. Employing a readily available low-valent rhenium carbonyl complex and a simple alcohol as a reducing agent, both terminal and internal vicinal diols are deoxygenated to olefins in good yield. The optional addition of acid (TsOH, H(2)SO(4)) provides access to lower reaction temperatures. This new system enables the transformation of a four-carbon sugar polyol into an oxygen-reduced compound, providing promising evidence for its practical application to produce unsaturated compounds from biomass-derived materials.

摘要

一种新型的邻二醇催化双脱氢方法被描述。使用易得的低价铼羰基配合物和简单醇作为还原剂,末端和内部邻二醇都能以良好的收率脱氧生成烯烃。可选地添加酸(TsOH、H(2)SO(4))可以降低反应温度。这个新体系使四碳糖多元醇转化为还原氧的化合物成为可能,为其实际应用于从生物质衍生材料中生产不饱和化合物提供了有希望的证据。
