The conversion of biomass into fuels and chemical feedstocks is one part of a drive to reduce the world's dependence on crude oil. For transportation fuels in particular, wholesale replacement of a fuel is logistically problematic, not least because of the infrastructure that is already in place. Here, we describe the catalytic defunctionalization of a series of biomass-derived molecules to provide linear alkanes suitable for use as transportation fuels. These biomass-derived molecules contain a variety of functional groups, including olefins, furan rings and carbonyl groups. We describe the removal of these in either a stepwise process or a one-pot process using common reagents and catalysts under mild reaction conditions to provide n-alkanes in good yields and with high selectivities. Our general synthetic approach is applicable to a range of precursors with different carbon content (chain length). This allows the selective generation of linear alkanes with carbon chain lengths between eight and sixteen carbons.

将生物质转化为燃料和化工原料是减少世界对原油依赖的举措之一。特别是对于运输燃料,整体替代燃料在物流上存在问题,尤其是因为现有基础设施的存在。在这里,我们描述了一系列生物质衍生分子的催化去功能化过程,以提供适合用作运输燃料的直链烷烃。这些生物质衍生分子包含各种官能团,包括烯烃、呋喃环和羰基。我们描述了在温和反应条件下,使用常见试剂和催化剂分步或一步工艺去除这些官能团,以提供高产率和高选择性的正烷烃。我们的一般合成方法适用于具有不同碳含量(链长)的一系列前体。这允许选择性地生成碳链长度在8到16个碳之间的直链烷烃。开发将生物质转化为燃料和化工原料的方法是减少世界对原油依赖的举措之一。在这里,描述了一系列生物质衍生分子的催化去功能化过程,这允许选择性地生成用作运输燃料的碳链长度在8到16之间的烷烃。
