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 [( [triple bond, length as m-dash] Si–O–)Zr(CH₃)₃(THF)₂] (minor) and [(Si–O–)₂Zr(CH₃)₂(THF)₂] (major) which have been characterized by SS NMR, IR, and elemental analysis. These supported pre-catalysts exhibit the best conversion of CO₂ to cyclic carbonates, as compared to the previously reported SOMC catalysts.
