The interesting effects of the linker and microenvironment on the recyclability of well-defined silica-supported catalysts were examined, which demonstrated the excellent activity and reusability for the ring-closingmetathesis (RCM) of a number of substrates.
A catalyst composition is provided, which may be used for ring closing metathesis. In the composition, a catalyst is immobilized on a siliceous mesocellular foam support. A suitable catalyst for use in the composition is a Grubbs-type catalyst or a Hoveyda-Grubbs-type catalyst.
