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 acetals.

通过使用稳定的芳基偶氮砜，开发了一种选择性的可见光驱动弱酸性（亚磺酸，在氮气吹扫的溶液中）或强酸性（磺酸，在氧气吹扫的溶液中）的生成方法。然后，这些砜被用于作为四氢吡喃基醚或缩醛的几种（取代）醇（和酚）的绿色、平稳和高效的光化学催化保护。
