patterns could be transformed into the corresponding phthalide products. Based on the mechanistic experimentation and reported prior studies, a possible mechanism for the benzylic oxidative lactonization reaction was proposed with the hypothetic photoactive ternary complex formed between the 2-alkylbenzoic acid substrate, magnesium ion, and bromate anion.
通过合并光催化和镁(铁、镍)催化,实现了温和实用的 C(sp 3 )-H 内酯化方案。具有多种取代模式的多种 2-烷基苯甲酸可以转化为相应的邻苯二甲酸产品。基于机理实验和先前报道的研究,提出了苄基氧化内酯化反应的可能机制,假设光活性三元络合物在 2-烷基苯甲酸底物、镁离子和溴酸盐阴离子之间形成。
