A photochemical halogen-bonding-assisted synthesis of vinyl sulfones via radical–radical cross-coupling of vinyl bromines and sodium sulfinates is developed. This methodology offers a facile and efficient approach to various vinyl sulfones with excellent functional group tolerance under metal-, photocatalyst-, base-, and oxidant-free conditions. The reaction is also applicable for the late-stage functionalization
通过乙烯基溴和亚磺酸钠的自由基-自由基交叉偶联,开发了一种光化学卤素键辅助合成乙烯基砜的方法。该方法为各种乙烯基砜提供了一种简便有效的方法,在无金属、光催化剂、碱和氧化剂的条件下具有优异的官能团耐受性。该反应也适用于药物分子的后期功能化和百克规模。此外,代替制备亚硫酸钠,这些反应也可以使用磺酰氯以一锅法进行。
