Abstract
Organosilicon Lewis acids supported on activated oxides and metal oxo complexes grafted on the organosilicon Lewis acids as heterogeneous catalysts and the related compositions, methods and systems are described. These organosilicon Lewis acids and the grafted metal oxo complexes catalyze industrially important chemical reactions including, respectively, C—F bond activation and olefin metathesis reactions such as homocoupling and polymerizations.
