The incorporation of sulfonate into mesoporous SBA-15 molecular sieves as ligands for palladium ions was used. Then SBA-15/PrSO3Pd and SBA-15/PrSO3PdNP were prepared and applied for the Heck arylation reaction of conjugate alkenes with aryl halides, to afford corresponding cross-coupling products under phosphine-free aerobic conditions with good to excellent yields. These supported palladium pre-catalysts could be separated easily from reaction products and reused several times, showing superiority over homogeneous catalysts for industrial and chemical applications.
