Hydroxylation of aryl sulfonium salts could be realized by utilizing acetohydroxamic acid and oxime as hydroxylative agents in the presence of cesium carbonate as a base, leading to a variety of structurally diverse hydroxylated arenes in 47–95% yields. In addition, the reaction exhibited broad functionality tolerance, and a range of important functional groups (e.g., cyano, nitro, sulfonyl, formyl
芳基锍盐的羟基化可以通过在碳酸铯作为碱存在下利用乙酰氧肟酸和肟作为羟基化剂来实现,从而产生多种结构多样的羟基化芳烃,产率为47-95%。此外,该反应表现出广泛的官能度耐受性,一系列重要的官能团(例如氰基、硝基、磺酰基、甲酰基、酮基和酯)可以很好地适应温和的反应条件。
