Abstract
Sterically demanding, sulfonated arylphosphine ligands have been applied to the aqueous-phase Heck and Suzuki coupling of aryl bromides. TXPTS promotes the aqueous-phase Heck coupling under mild conditions and provides good yields of coupling products from aryl bromides at 80°C. Active catalysts for Suzuki couplings of aryl bromides at 50°C and 80°C are described.
