将生物质转化为燃料和化学原料是减少世界对原油依赖的努力的一部分。尤其是对于运输燃料来说，批量更换燃料在后勤上存在问题，尤其是因为已经到位的基础设施。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，以提供适合用作运输燃料的直链烷烃。这些生物质衍生的分子含有各种官能团，包括烯烃、呋喃环和羰基。我们描述了在温和的反应条件下使用普通试剂和催化剂以分步方法或一锅法去除这些正构烷烃，以提供良好的产率和高选择性。我们的一般合成方法适用于一系列具有不同碳含量（链长）的前体。这允许选择性地产生碳链长度在八个碳和十六个碳之间的直链烷烃。
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.
