Schrock carbene complex Mo(=CHCMe2Ph)(=N-2,6-i-Pr2C6H3)[OCMe(CF3)(2)](2) was immobilized on mesoporous molecular sieves MCM-41 via a ligand exchange reaction with OH surface groups. The heterogeneous catalyst prepared in this way was Mo-leaching resistant and exhibited high activity and selectivity in metathesis of neat 1-heptene. The catalyst activity in cross-metathesis of 1-heptene with norbornene and cyclooctene was also studied. (c) 2005 Elsevier B.V. All rights reserved.
