Abstract
AbstractThe synthesis and characterization of Ru complexes of the type [L2X2RuCHR] (L=PPh3, PCy3, N‐heterocyclic carbenes or their derivates; X=Cl) grafted on mesoporous SBA‐15 material are described. In this heterogeneous catalyst the Ru complexes are anchored in the pore channels of mesoporous silica material SBA‐15 to prevent the decomposition of the catalytic species. Compared with formal organic‐supported heterogeneous catalysts, this heterogeneous catalyst shows relatively high catalytic activity in olefin metathesis reactions and can be used several times without any decrease in catalytic activities.
