Abstract

A well-defined silica-supported molybdenum dioxo species, ([triple bond, length as m-dash]SiO)2Mo(O)2, is prepared by grafting Mo(O)2[OSi(OtBu)3]2 on partially dehydroxylated silica SiO2-700, followed by thermal treatment under high-vaccum and calcination. Activated by an organosilicon agent the resulting material is active for olefin metathesis at 30 °C.
