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 CB bond under mild conditions. A wide range of functional groups are tolerated, making this method particularly useful for the borylation of functionalized aromatics.

Palladium‐catalyzed coupling between aryl chlorides and diisopropylaminoborane leads to the formation of a C—B bond under mild conditions and in the presence of pinacol, the corresponding pinacol boronate esters are obtained in high yields.
