Organometallic Reagents 2 From Metallated Phosphines

The mechanism involves oxidative addition of the halide or triflate to the initial palladiumfO phosphine complex to form a palladium(II) species. The key slow step is a transmetallation, so calk because the nucleophile (R1) is transferred from the metal in the organometallic reagent to the palla dium and the counterion (X = halide or triflate) moves in the opposite direction. The new palladi um(II) complex with two organic ligands undergoes reductive elimination to give the couple product and the palladium(O) catalyst ready for another cycle. [Pg.1324]
