Non-classical ruthenium hydride complexes are promising lead structures for the C-H bond activation and functionalization of aromatic compounds. In the present paper, the preparation and crystallographic characterisation of the first organo-metallic complexes bearing dihydrogen ligands and N-heterocyclic carbene ligands in the same coordination sphere are described. The mixed phosphine/ carbene complex [(IMes)Ru(H)2(H2) 2(PCy3)] (IMes = 1,3-dimesityl-1,3-dihydro-2H-imidazol-2- ylidene; 3a) shows a unique reactivity pattern in the inter- and intramolecular activation of C-H bonds. In particular, complex 3a effects a rapid and remarkably selective intermolecular activation of sp2 C-H bonds in simple aromatic compounds at room temperature.
