Tungsten oxo alkyl species
A well-defined, silica-supported
tungsten oxo alkyl species prepared by the surface organometallic
chemistry approach displays high and sustained activity in propene metathesis. Remarkably, its catalytic performances outpace those of the parent imido derivative, underlining the importance of the oxo ligand in the design of robust catalysts.
