Synthesis of Biaryl Phosphine Palladium(0) Precatalysts

Well-defined palladium precatalysts have become increasingly important in cross-coupling chemistry. Despite the wide choice of complexes available today, palladium(0) compounds bearing Buchwald's biaryl phosphines are still under-represented. We present here an efficient and facile synthesis of biaryl phosphine palladium(0) complexes supported by a divinyltetramethyldisiloxane (dvtms) ligand. Starting from commercially available [Pd(allyl)Cl]2, a variety of [Pd(L)(dvtms)] complexes can be accessed in high yields under mild reaction conditions. Their catalytic activity was tested in Buchwald-Hartwig couplings and found to be very good for both (hetero)aryl bromides and chlorides.
