Abstract

This paper reports the synthesis and characterization of a variety of ruthenium complexes coordinated with phosphine and N-heterocyclic carbene (NHC) ligands. These complexes include several alkylidene derivatives of the general formula (NHC)(PR3)(Cl) 2Ru CHR', which are highly active olefin metathesis catalysts. Although these catalysts can be prepared adequately by the reaction of bis (phosphine) ruthenium alkylidene precursors with free ...
