Vanadium Oxo Organometallic Species Supported on Silica for the Selective Non-oxidative Dehydrogenation of Propane
Abstract
The molecular complex [V(=O)(Mes)₃] (1) reacts with silica partially dehydroxylated at 700°C (SiO₂-700) to afford [(≡SiO)V(=O)(Mes)₂] (2) as major surface species, while a bis-grafted surface species [(≡SiO)₂V(=O)(Mes)] (3) is obtained on SiO₂₋₂₀₀. These surface species were characterized by DRIFT, RAMAN, ¹H, ¹³C and ⁵¹V solid state NMR and XAFS spectroscopies and show an activity in non-oxidative dehydrogenation of propane at 500 °C. The bipodal surface organometallic complex displays a higher selectivity in propylene compared to the monopodal species.
