The synthesis of arylboronic ester derivatives from aryl chlorides by using aryl(amino)boranes is described. Palladium‐catalyzed coupling between aryl chlorides and diisopropylaminoborane leads to the formation of a CB bond under mild conditions. A wide range of functional groups are tolerated, making this method particularly useful for the borylation of functionalized aromatics.
描述了通过使用芳基(氨基)硼烷从芳基氯化物合成芳基硼酸酯衍生物。在温和条件下,芳基氯化物和二异丙基氨基硼烷之间的钯催化偶联导致形成CB键。宽泛的官能团是可以容忍的,这使得该方法对官能化芳族化合物的硼酸酯化特别有用。
