Metal-catalyzed B–C and C–C bond-forming reactions of organoboronic acids that have been pursued in the past three decades by our group are summarized in this article. B–C bond-forming reactions for the synthesis of organoboronic acid derivatives include metal- catalyzed addition reactions of pinacolborane or catecholborane (hydroboration), bis (pinacolato) diboron (diboration), and alkylthioboranes (thioboration) to alkenes, alkynes, ...
