A novel rongalite-promoted metal-free aerobic ipso-hydroxylation of arylboronic acids has been developed. This method employs low-cost rongalite as a radical initiator and O₂ as a green oxidizing agent for ipso-hydroxylation. This protocol is compatible with a wide variety of functional groups with good to excellent yields at room temperature. Furthermore, mechanistic insight into the role of superoxide radical anions in C-B cleavage has also been provided based on DFT studies.

雕白粉促进的无金属有氧本位芳基硼酸在阳光下的羟基化：DFT机理的研究

已开发出一种新的由芳铁矿促进的芳基硼酸促进的无金属有氧ipso-羟基化的金属。该方法采用低成本的人造石作为自由基引发剂，并采用O ₂作为绿色的氧化剂进行异丙基羟基化。该方案与各种官能团兼容，在室温下具有良好或优异的收率。此外，基于DFT研究还提供了对超氧自由基阴离子在CB裂解中作用的机理的见解。
