Abstract

Abstract A series of ruthenium-based olefin metathesis catalysts coordinated with unsymmetrical N-heterocyclic carbene (NHC) ligands has been prepared and fully characterized. These complexes are readily accessible in one or two steps from commercially available [(PCy 3) 2 Cl 2 Ru [DOUBLE BOND] CHPh]. All of the complexes reported herein promote the ring-closing of diethyldiallyl and diethylallylmethallyl ...
