A series of new carboxyl Pd(Ⅱ)complexes were prepared from organic silica via immobilization on MCM-41 molecular sieve
and characterized with XRD,XPS,FT-IR and FT-Raman techniques.The results showed that —COOH groups could be immobilized on the MCM-41 surface via a reaction of the silanol groups with oxyalky-silane compounds
and the organically modified MCM-41 materials retained its hexagonally-packed porous structure during supporting organic species
but internal surface area and pore diameter of the materials decreased markedly.The direct binding to silica surfaces was achieved by direct ligands exchange of MCM-41 supported caboxylate group ligands with Pd(OAc)2.
