Palladium-catalyzed couplings are very powerful tools for the formation of CÀC linkages.[1] A typical cross-coupling reaction involves the combination of an electrophile with a nucleophile in the presence of a metal catalyst. The classical nucleophilic components are organometallic reagents derived from, for example, magnesium,[2] boron,[3] silicon,[4] tin,[5] and zinc,[6] whereas the electrophiles are generally organic halides or sulfonates. Thus, a ...
