The synthesis and characterization of two new ruthenium indenylidene complexes [RuCl(2)(SIPr)(Py)-(Ind)] 6 and [RuCl(2)(SIPr) (3-BrPy)-(Ind)] 7 featuring the sterically demanding N-heterocyclic carbene 1,3-bis(2,6-di isopropylphenyl)-4,5-dihydroimidazol-2-ylidene (SIPr) are reported. Remarkable activity was ob-served with these complexes in ring closing, enyne, and cross metathesis of olefins at low catalyst loadings. The performance of SIPr-bearing complexes 6 and 7 as well as [RuCl(2)(SIPr) (PCy(3))-(Ind)] 5 in ring opening metathesis polymerization is also disclosed. This work highlights the enormous influence of the neutral spectator ligands on catalyst activity and stability.
