title: N-heterocyclic carbenes of iridium(I): ligand effects on the catalytic activity in transfer hydrogenation.
abstract: New Ir-NHC complexes based on different heterocyclic moieties like imidazole, benzimidazole and imidazolidine are presented and tested in transfer hydrogenation catalysis. A broad range of steric and electronic properties of NHC ligands is covered to give an idea for catalyst design from the experimental point of view.
