Abstract
Ruthenium complex 3b bearing chelating carboxylate ligand was immobilized on mesoporous molecular sieve SBA-15 via cleavage of carboxylate by fluorocarboxylic acid groups introduced on the support surface. The hybrid olefin metathesis catalyst Ru/L/SBA-15, prepared straightforward without use of silver salts, exhibited high activity and selectivity in model metathesis reactions and low ruthenium leaching.
