The interaction of [W(C–tBu)(CH2–tBu)(OAr)2] (Ar = 2,6-iPr2C6H3) (1), with the hydroxyl groups of a silica dehydroxylated at 700 °C leads to [(SiO)W(OAr)2(C–tBu)] (2) which was characterized by IR, solid-state NMR and mass balance analysis. This well-defined surface species is an efficient catalyst for the metathesis of pent-2-yne.
