Abstract

Grafting of [W₂(NMe₂)₆] onto dehydroxylated silica affords the well-defined surface species [( [triple bond, length as m-dash] Si–O)W₂(NMe₂)₅], characterized by elemental analysis, and infrared, Raman and NMR spectroscopies, and the catalytic reactivity of this supported tungsten(III) d³–d³ dimer and of its alkoxide derivatives towards alkynes has been probed.
