metal‐free arylative coupling of carboxylic acids using iodosoarenes without the use of a catalyst and base, which is applicable to even a highly‐polar molecule bearing multiple alcohol groups, is reported. The in situ preparation of the reactive diaryliodonium(III) carboxylates is the important key to this approach, and the introduction of the trimethoxybenzene auxiliary enables both the smooth salt
据报道,在不使用催化剂和碱的情况下,使用碘代芳烃进行的羧酸金属无芳基偶合,甚至适用于带有多个醇基的高极性分子。在原位制备的二芳基碘反应(III)的羧酸酯的是这种方法的重要的关键,并引入了三甲氧基苯辅助的使平滑盐层和联接器期间选择性芳转移事件两者。
