Effect of Ligand Bulk in Ruthenium-Catalyzed Olefin Metathesis: IPr* vs IPr
dataset

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.
