The selective visible-light-driven generation of a weak acid (sulfinic acid, in nitrogen-purged solutions) or a strong acid (sulfonic acid, in oxygen-purged solutions) by using shelf-stable arylazo sulfones was developed. These sulfones were then used for the green, smooth, and efficient photochemical catalytic protection of several (substituted) alcohols (and phenols) as tetrahydropyranyl ethers or
通过使用货架稳定的芳基偶氮砜,开发了选择性可见光驱动的弱酸(亚
磺酸,在氮气吹扫溶液中)或强酸(
磺酸,在
氧气吹扫溶液中)的产生。然后,这些砜被用于作为
四氢吡喃醚或
缩醛对几种(取代的)醇(和
酚)进行绿色、平滑和高效的光
