Synthesis of imidazolium-tagged ruthenium carbene complex: Remarkable activity and reusability in regard to olefin metathesis in ionic liquids

摘要

We have demonstrated the synthesis of a new ionic liquid supported ruthenium carbene complex 1a,b and its applications to olefin metathesis. These catalysts can be used for ring-closing metathesis in the construction of five-to-eight-membered rings with high activity and good recyclability.
