regioselective chlorination of arenes, yielding almost exclusively the monochlorinated product. It tolerates free hydroxy groups, 1°, 2° and 3° amines, and carboxylic acids, among other polar and nonpolar functional groups, as well as mono- and polysubstituted aromatic rings. Additionally, the utilization of chlorosulfonium salts as the chlorinating agent is demonstrated. The method emerges as an alternative
该手稿提出了芳烃的区域选择性氯化,几乎完全产生一氯化产物。它可耐受游离羟基、1°、2° 和 3° 胺、羧酸、其他极性和非极性官能团以及单取代和多取代的芳环。此外,还证明了使用氯锍盐作为氯化剂。该方法是作为其他必须从反应混合物中分离有机副产物的工艺的替代方案。此外,主要副产物是气态物质,例如CO和CO 2。该出版物介绍了亚砜、草酰氯和过氧化氢水溶液作为氯化混合物的应用。
