Docking of Tetra-methyl Zirconium to the Surface of Silica: A Well-Defined Pre-catalyst for Conversion of CO2 to Cyclic Carbonates

Abstract
The metal complex (Zr(CH3)4(THF)2) has been fully synthesized, characterized and grafted onto partially dehydroxylated silica to give two surface species -$. / /' $ %3)3(THF)2] (minor) and -$. / /'2Zr(CH3)2(THF)2] $ (major) which have been characterized by SS NMR, IR, elemental analysis. These supported pre-catalysts exhibit the best conversion of CO2 to cyclic carbonates, as compared to the previously reported SOMC catalysts.
