fuels and bulk chemicals. Herein, we present a survey of reagents for selective stepwise oxidation of lignin model compounds. Specifically, we have targeted the oxidative cleavage of Calpha-Cbeta bonds as a means to depolymerize lignin and obtain useful aromatic compounds. In this work, we prepared several lignin model compounds that possess structures, characteristic reactivity, and linkages closely
木质素是衍生自植物的无定形芳族聚合物,是燃料和散装
化学品的潜在来源。在此,我们对
木质素模型化合物的选择性逐步氧化试剂进行了概述。具体而言,我们已针对Calpha-Cbeta键的氧化裂解,以解聚
木质素并获得有用的芳香族化合物的手段。在这项工作中,我们制备了几种
木质素模型化合物,这些化合物具有与母体
木质素聚合物密切相关的结构,特征反应性和键。我们观察到苄基羟基的选择性氧化,然后所得酮的Baeyer-Villiger氧化,成功地裂解了这些模型化合物中的Calpha-Cbeta键。
