Boronic acids are used extensively in organic chemistry as chemical building blocks and intermediates predominantly in the Suzuki coupling. A key concept in its chemistry is transmetallation of its organic residue to a transition metal.
Arylboronic acids and their esters are highly popular synthetic intermediates in organic synthesis both for their ease of conversion to other functional groups (such as phenols and aryl halides) and to their efficient Pd-catalyzed coupling with aryl or vinyl halides or triflates to form biaryl and alkyl aryl derivatives.
