Comparison of metathesis activity of catalysts prepared by anchoring of MoO 2 (acac) 2 on various supports

The properties and olefin metathesis activity of molybdena–alumina, molybdena–silica–alumina and molybdena–silica catalysts prepared by anchoring of MoO 2 (acac) 2 complex were compared. The specific activity obtained for molybdena–silica–alumina system is higher than that of molybdena–alumina and molybdena–silica catalysts. This statement concerns also the catalysts treated with tetramethyltin
