Abstract: A series of novel ruthenium(II) complexes with nitron-type N-heterocyclic carbene ligands containing chelating (N-arylcarbamoyl)methyl or carboxymethyl groups have been synthesized. Their evaluation as precatalysts in the hydrogenation of ketones has revealed that the complex containing three N-mesityl groups (one on the carbamoyl- methyl moiety and two on the triazole moiety) is the most efficient one.

Keywords: ruthenium complexes, N-heterocyclic carbene, Nitron, chelating ligands, hemilabile, catalysis, transfer hydrogenation, ketones, secondary alcohols.
