Abstract

Air-stable titanocene bis (perfluorooctanesulfonate)[Cp2Ti (OSO2C8F17) 2] that shows high Lewis acidity was prepared from Cp2TiCl2 and AgOSO2C8F17. The compound was characterized by different techniques, and examined as a catalyst for acylation reactions. It was found that using equimolar acetic anhydride as acetylating agent and under solvent- free condition, Cp2Ti (OSO2C8F17) 2 exhibits high activity and selectivity in the ...
