To tether a tungsten: A hybrid material, featuring single-site phenolic functionalities on a silica surface was developed and subsequently used to tether a tungstenocarbyne complex. Drastic improvements in terms of activity and stability in propene metathesis were observed with respect to the silica counterpart. Further tuning of the spacer moiety with fluorine atoms led to additional significant improvements in activity.
