CATALYSTS FOR RING-CLOSING METATHESIS

摘要

PROBLEM TO BE SOLVED: To provide a catalyst composition which may be used for ring closing metathesis for synthesizing cyclic compounds.SOLUTION: In the composition, a catalyst is immobilized on a siliceous mesocellular foam support using a linking group comprising a carbamate or silyl group. A suitable catalyst for use in the composition is a Grubbs-type catalyst or a Hoveyda-Grubbs-type catalyst, being an organic metal complex catalyst containing ruthenium.
