Abstract: In this present work the amine ligands embedded into the ordered silica mesoporous (PdX 2@SBA-15/Y, Y=1,2) as solid support for palladium complexes was designed. Among all of them, the covalently bonded Pd(OAc)2 /ethylenediamine complex into SBA-15 shows superior activity and selectivity toward Suzuki-Miyaura cross-coupling in aerobic condition with excellent yields. The as synthesized catalyst could be separated easily from reaction products and used for at least 10 times.
