We developed a one-pot method for the generation of benzynes from a range of readily available 2-hydroxyphenylboronic acids. This method features the in situ activation of both boronic acid and hydroxyl groups of the substrate to enhance benzyne generation at 60 °C. Such mild conditions facilitate the generation of functionalized benzynes that immediately react with diverse arynophiles to produce multisubstituted
我们开发了一种一锅法,可从一系列容易获得的2-羟基苯基硼酸中生成苯炔。该方法的特点是原位活化硼酸和底物的羟基,以增强60°C下苯并炔的生成。这种温和的条件促进了官能化的苯并炔的生成,该苯并炔立即与各种亲核体反应生成多取代的稠合苯。
