Abstract

Anchoring titanium: Grafting of TiCl4 to site-isolated silanol groups on silica initially leads to freely rotating species. Upon heating, a thermal restructuring takes place, causing the elimination of TiCl4 and the formation of more strongly anchored titanium species, which were found to be highly active and stable epoxidation catalysts.
