Abstract

An efficient method for the preparation of backbone-substituted imidazolinium salts for use as N-heterocyclic carbene ligands, e.g., for organometallic catalysts is provided. These functionalized N-heterocyclic carbene ligands are used to prepare solid-supported catalysts, e.g., for olefin metathesis.
