An Amphiphilic Resin-Supported Palladium Catalyst for High-Throughput Cross-Coupling in Water

The Suzuki−Miyaura coupling of aryl halides (8 varieties) and aryl- or vinylboronic acids (12 varieties) took place in water in the presence of a palladium complex of an amphiphilic polystyrene−poly(ethylene glycol) copolymer resin-supported N-anchored 2-aza-1,3-bis(diphenylphosphino)propane ligand and potassium carbonate to give uniform and quantitative yields of the corresponding biaryls (96 varieties).
