A new heterogeneous metathesis catalyst: preparation and activity of a highly active catalyst for the metathesis of pent-2-ene

Abstract

Very promising heterogeneous metathesis catalysts are developed based on aryloxy tungsten complexes anchored on a NbO_x/SiO₂ support; upon activation with BuⁱAlCl₂, highly active and long-lived systems are formed; the nature of the aryloxy ligands affects the activity of the system.
