achieved via photocatalysis. This protocol exhibits a broad scope of lignin models and excellent compatibility of functionalization reagents, constructing a series of functionalized lignin-based aromatic compounds. Highly selective formation of alkyl radical species through a proton-coupled electron transfer and β-scission process provides the opportunity to form new C–C and C–N bonds by reaction with
通过光催化实现了一种温和有效的木质素 β-O-4 裂解和功能化方法。该方案展示了广泛的木质素模型和功能化试剂的良好兼容性,构建了一系列功能化的木质素基芳香族化合物。通过质子耦合电子转移和β-断裂过程高度选择性地形成烷基自由基物种,提供了通过与亲电试剂反应形成新的C-C和C-N键的机会。
