Biphenylene-substituted ruthenocenylphosphine for Suzuki-Miyaura coupling of sterically hindered aryl bromides.
A highly general, active, and stable catalytic system was realized in the palladium-catalyzed Suzuki-Miyaura reactions of sterically hindered aryl bromides with arylboronic acids using biphenylene-substituted di-tert-butylruthenocenylphosphine (R-Phos) as a supporting ligand.
