The electrochemical and catalytic behavior of these new complexes was compared with the conventional NHC carbene Hoveyda II IMes-type complexes 1 and 2 for ring closing metathesis reactions.Reserva de todos los derechosFace donor propertiesOlefin metathesisImidazolin-2-Ylidene ligandsImidazol-2-Ylidene ligandsCross-metathesisCatalystsMetalEfficientBearingRcmSynthesis and characterization of new ruthenium N-heterocyclic carbene Hoveyda II-type complexes.
