A Hoveyda–Grubbs‐Type Olefin Metathesis Catalyst Bearing a Fluorinated Unsymmetrical NHC Ligand
European Journal of Inorganic Chemistry, EarlyView.A fluorinated unsymmetrical NHC ruthenium complex was synthesised and employed as a catalyst for olefin metathesis reactions. The modification of the steric and electronic properties of the NHC ligand through the introduction of fluorine substituents results in improved activity but lower selectivity compared to the analogous non‐fluorinated NHC ...
