Abstract

The interaction of [W({triple bond, long}C-tBu)(CH₂-tBu)(OAr)₂] (Ar = 2,6-iPr₂C₆H₃) (1), with the hydroxyl groups of a silica dehydroxylated at 700 °C leads to [({triple bond, long}SiO)W(OAr)₂({triple bond, long}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.
