通过将Mo（O）_2 [OSi（OtBu）_3]_2接枝到部分脱羟基的SiO_2 -700上，然后在高真空下热处理和煅烧，制备了一种结构明确的SiO_2负载的二氧钼物种（[三键，长度为m-dash]SiO）_2Mo（O）_2。通过有机硅试剂活化，所得材料在30 °C下对烯烃复分解具有活性。
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.
