catalysis has been developed to achieve oxidativeC–H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp2)–H bonds over C(sp3)–H bonds. The method has been used for the chlorination of a diverse set of substrates, including the expedited synthesis of key intermediates to bioactive
已开发出光氧化还原催化以使用NaCl作为氯源和Na 2 S 2 O 8作为氧化剂实现芳族化合物的CH-H氧化氯化。该反应在室温下发生,对C(sp 2)–H键的选择性高于C(sp 3)–H键的选择性。该方法已用于多种底物的氯化,包括加速合成生物活性化合物和药物的关键中间体。
