Abstract
  • High-throughput screening of triphenylphosphine-based polymer-supported homogeneous catalysts(e.g., FibreCatTM-1001) and selected Johnson MattheyPd/C catalysts has achieved nearly quantitative conversion of activated and unactivated aryl bromides inSuzuki coupling using an ethanol−water solvent system.For more challenging substrates such as p-chloroacetophenone and 3-bromothiophene, coupling could bepossible by tuning the FibreCat catalysts with t-Bu3P.These tuned catalysts (TunaCat) are air-stable.
  • The synthesis of several examples of polyethylene (fiber)-based supported homogeneous Pd catalysts and their applications in Suzuki coupling using high-throughput screening studies have been described.
