The Ru-containing modified silica [Ru-II(terpy)(4'Mebpy/4CONH(CH2)(3)SiO3/2)Cl](+)m center dot zSiO(2) has been prepared by covalent attachment on silica surface of biomimetic [Ru-II(terpy)(4-CO2H-4'-Mebpy)Cl](+). complex through the formation of a pseudo-peptide bond. The catalytic ability of bio-derived silica for alkene oxidation with (HOOBu)-Bu-t has been evaluated exhibiting significant efficiency and, in some cases, showing increased activity compared vs. the corresponding 'net' [Ru-II(terpy)(4-CO2H-4'-Mebpy)Cl](+) complex. The data supported that the covalently attached ruthenium complex preserves the catalytic behaviour of the 'net' ruthenium complex indicating that the presented grafting process was successful.
