Abstract

Abstract Two new ruthenium complexes bearing a bidentate (κ 2 O, C)-isopropoxy– indenylidene ligand and a PPh 3 (9) or PCy 3 (10, Cy= cyclohexyl) ligand have been synthesized and fully characterized by 1 H and 13 C NMR spectroscopy and X-ray crystallography. Complex 10 displays a very high thermal stability with a half life of six days at 110 C in [D 8] toluene. Complex 10 was evaluated in various ring-closing metathesis ...
