Abstract
Abstract The palladium-catalyzed cross-coupling reaction between different types of organoboron compounds and various organic halides or triflates in the presence of base provides a powerful and general methodology for the formation of carbon–carbon bonds. The Csp2–B compounds (such as aryl- and 1-alkenylboron derivatives) and Csp3–B compounds (alkylboron compounds) readily cross-couple with organic electrophiles to give coupled products selectively in high yields. Recently, the Csp–B compounds (1-alkynylboron derivatives) have been also observed to react with organic electrophiles to produce expected cross-coupled products. The overview of some of such coupling reactions is discussed here in this article.
