  • Selective upgrading of biomass-derived benzylic ketones by (formic acid)–Pd/HPC–NH2 system with high efficiency under ambient conditions
    作者:Honghui Ning、Yuzhuo Chen、Zhenzhen Wang、Shanjun Mao、Zhirong Chen、Yutong Gong、Yong Wang

    exhibits unprecedented performance for the selective HDO of benzylic ketones from crude lignin-derived oxygenates. Designed experiments and theoretical calculations reveal that the H+/H− species generated from FA decomposition accelerates nucleophilic attack on carbonyl carbon in benzylic ketones and the formate species formed via the esterification of intermediate alcohol with FA expedites the cleavage
    升级生物质衍生的酚类化合物为生产高附加值的燃料和化学品提供了一种有价值的方法。然而,大多数成熟的催化系统即使在苛刻的反应条件下也表现出低加氢脱氧 (HDO) 活性。在这里,我们发现以甲酸 (FA) 为氢源的–NH 2修饰的分级多孔碳 (Pd/HPC–NH 2 ) 上负载的 Pd 对来自粗木质素衍生的含氧化合物的苄基酮的选择性 HDO 表现出前所未有的性能。设计的实验和理论计算表明 H + /H -FA 分解产生的物种加速了对苄基酮中羰基碳的亲核攻击,通过中间醇与 FA 的酯化形成的甲酸盐物种加速了 C-O 键的断裂,在 30°C 下实现了香兰素152.5 h -1的 TOF升级,比传统 HDO 工艺(~10 h -1,100°C–300°C)高 15 倍。这项工作提供了一条有趣的绿色途径,可以在温和的条件下仅从生物质中生产运输燃料或有价值的化学品。
  • Cu(OAc)<sub>2</sub>-catalyzed remote benzylic C(sp<sup>3</sup>)–H oxyfunctionalization for CO formation directed by the hindered para-hydroxyl group with ambient air as the terminal oxidant under ligand- and additive-free conditions

    A hindered para-hydroxyl group-directed remote benzylic C(sp3)–H oxyfunctionalization has been developed for the straightforward transformation of 2,6-disubstituted 4-cresols, 4-alkylphenols, 4-hydroxybenzyl alcohols and 4-hydroxybenzyl alkyl ethers into various aromatic carbonyl compounds. The ligand- and additive-free Cu(OAc)2-catalyzed atmospheric oxidation mediated by ethylene glycol unlocks a
    已经开发了一种受阻的对羟基定向的远程苄基C(sp 3)–H氧官能团,用于将2,6-二取代的4-甲酚,4-烷基苯酚,4-羟基苄醇和4-羟基苄基烷基醚直接转化为各种芳族羰基化合物。由乙二醇介导的无配体和无添加剂的Cu(OAc)2催化的大气氧化作用,可以使伯苄基和仲苄基官能化,形成简便,原子经济且对环境无害的C O形成。由于4-羟基苯甲醛和4-羟基苯酮的药物重要性,因此该方法对于基础研究和实际应用均具有重要价值。
