Use of Re(C5H7O2) in preparation of catalysts for olefin metathesis

New catalysts for olefin metathesis are obtained upon interaction between rhenium trisacetylacetonate and -Al₂O₃ surface. After high temperature treatment in flows of O₂ and N₂ and addition of organometallic compound as a cocatalyst the activity of the resulting catalyst exceeds that of known Re/Al₂O₃ catalysts prepared by impregnation. The catalysts exhibit maximal activity at a cocatalyst surface concentration of 3 × 10^–7 mol/m². Further increase of the cocatalyst concentration leads to deactivation.
