A well-defined, silica-supported molybdenum oxo alkyl species, ([triple bond, length as m-dash]SiO-) 2 Mo([double bond, length as m-dash]O)(CH 2 Bu) 2 , was prepared by the selective grafting of Mo([double bond, length as m-dash]O)(CH 2 Bu) 3 Cl onto a silica partially dehydroxylated at 200 °C using a rigorous surface organometallic chemistry approach. The immobilized bipodal surface species, partly resembling the active species of industrial MoO 3 /SiO 2 olefin metathesis catalysts, exhibited excellent functional group tolerance in conjunction with its high activity in homocoupling, self and ring closing olefin metathesis.
