摘要

在胶束催化的辅助下，通过在水中进行 C-H 功能化，开发出了一种环境可持续的、多功能的和具有成本效益的 C-Se 和 C-X（X = I、Br 和 Cl）键形成方法。该反应使用了最低量的二芳基二硒化物和卤化钾进行相应的官能化。本方案适用于放大合成，可直接提供所需的硒化产物，无需色谱纯化，纯度也足够高。水性胶束催化系统可重复使用多达 5 个反应周期，而不会影响反应产率。

Micelle-Assisted C(sp2)–H Functionalization for C–Se and C–X Bond Formation in the Aqueous Medium

An environmentally sustainable, versatile, and cost-effective approach for C–Se and C–X (X = I, Br, and Cl) bond formation through C–H functionalization assisted by micellar catalysis in water is developed. The reaction utilizes a minimum amount of diorganyl diselenides and potassium halides for the respective functionalizations. The present protocol was suitable for scale-up synthesis, which directly provided the desired selenylated products without the need for chromatographic purification, in sufficient purity. The aqueous micellar catalysis system was reusable for up to 5 reaction cycles without compromising the reaction yield.
