The Ru-containing modified silica [RuII(terpy)(4′Mebpy/4CONH(CH2)3SiO3/2)Cl]+m·zSiO2 has been prepared by covalent attachment on silica surface of biomimetic [RuII(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 HOOtBu has been evaluated exhibiting significant efficiency and, in some cases, showing increased activity compared vs. the corresponding ‘net’ [RuII(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.
Graphical abstractThe synthesis of supported complex [RuII(terpy)(4’Mebpy/4CONH(CH2)3SiO3/2)Cl]+m by covalent attachment on silica surface of biomimetic [RuII(terpy)(4-CO2H-4’-Mebpy)Cl]+ complex and its catalytic ability for alkene oxidation with HOOtBu are presented here.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► A Ru(II)-complex has been grafted on silica surface. ► The covalent attachment was achieved by the formation of a pseudo-peptide bond. ► The Ru-containing bio-derived material has been evaluated as heterogeneous catalyst for olefin oxidation with HOOtBu.
