Isostructural Molecular and Surface Mimics of the Active Sites of the Industrial WO3/SiO2 Metathesis Catalysts #chempaperaday 243

"Silica-supported tungsten oxide has become a key catalyst of the petrochemical industry as part of the Lummus OCT process, allowing the production of propylene through the ethenolysis of butenes.(1, 2) Despite the now well-accepted Chauvin mechanism, alkylidenes and metallacyclobutane intermediates have however never been observed in such systems"
So, it is always worth trying to synthesize well defined supported mimics of these.
A very short but a really good paper. Great examples of synthetic work and problem solving. I am loving it.
