Abstract

Rhodium supported on titania-silica is modeled by 1, which was obtained from [{Cp*TiMe(μ-O₂ SiPh₂ )}₂ ] (2) and [{Rh(OH)(cod)}₂ ]. Complex 2 and its triply bridged derivative [Cp*Ti(μ-O₂ SiPh₂ )₃ TiCp*] (3) can be envisaged as molecular models of titania-silica systems. Compounds 1-3 could potentially provide insights into the nature of the catalytically active sites in these systems; cod=1,5-cycloctadiene, Cp*=η⁵ -C₅ Me₅ .

Keywords: O ligands; bridging ligands; rhodium; titanium.
