Abstract
Novel ruthenium catalysts, [RuCl2(IPr*)(PPh3)(3-phenylindenylidene)]
(1) and [RuCl2
(IPr*)(Py)(3-phenylindenylidene)]
(2), bearing the very bulky ligand IPr* are reported. The complexes
were tested in ring closing and cross-metathesis, and their activities were
compared to that displayed by [RuCl2(IPr)(PPh3)(3-phenylindenylidene)]
(3) and the new [RuCl2(IPr)(Py)(3-phenylindenylidene)] (4),
in order to assess how the steric hindrance of the N-heterocyclic carbene
influences the catalytic activity of the resulting ruthenium complexes
