  The estimated excited oxidation potential of sodium anthraquinone‐2‐sulfonate (SAS) increases from 1.8 V to about 2.3 V vs SCE by protonation with Brønsted acids. This increased photooxidation power of protonated anthraquinone was used for the regio‐selective oxidative bromination of electron rich (hetero)arenes and drugs in good yield. The mild reaction conditions are compatible with many functional

  通过布朗斯台德酸的质子化，蒽醌-2-磺酸钠（SAS）的估计激发氧化电势相对于SCE从1.8 V增加到约2.3V。质子化蒽醌提高的光氧化能力可用于富电子（杂）芳烃和药物的区域选择性氧化溴化，收率很好。温和的反应条件与许多官能团兼容，例如双键和三键，酮，酰胺和胺，羟基，羧酸和氨基甲酸酯。机理研究表明，芳烃的光氧化反应继之以亲核性溴化物添加是可能的途径。
