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.
通过将Mo(O)2[OSi(OtBu)3]2接枝到部分脱羟基的二氧化硅SiO2-700上，然后在高真空下进行热处理和煅烧，制备出一种明确的二氧化硅负载的二氧钼物种，([三键，长度为m破折号]SiO)2Mo(O)2。经有机硅试剂活化后，所得材料在30℃下对烯烃复分解反应具有活性。
