本文报道了一种光诱导钌催化的烷基苯酚 C-H 活化反应。与传统热反应相比,该方法条件温和,官能团耐受性良好,可实现高效后期官能化。机理研究表明,反应涉及光激发钌环中间体的单电子转移(SET)途径。

关键词: 间位选择性, 光催化氧化还原, 钌催化, 后期官能化

We disclose a photo-induced ruthenium-catalyzed meta-alkylation of phenol derivatives. Compared with conventional thermal reactions, it features mild conditions and good functional group tolerance, thus allowing efficient late-stage functionalization. Mechanistic studies reveal a single-electron transfer (SET) pathway involving a photo-excited ruthenacycle intermediate.

Key words: meta-selectivity, photoredox catalysis, ruthenium catalysis, late-stage functionalization
