Synthesis of functionalised N-heterocyclic carbene ligands bearing a long spacer and their use in olefin metathesis

Author affiliations

Abstract

A synthetic route to backbone functionalised imidazolinium salts—NHC ligand precursors has been developed. These tagged NHC ligands can be used to obtain a homogeneous Hoveyda-type catalyst (19) containing a quaternary ammonium group on a C-8 long spacer. Products of olefin metathesis reactions promoted by complex 19 can be readily purified from Ru-residues by filtration of the reaction mixture through a small amount of silica gel.
