✦ Synopsis

The dihydride ruthenium N-heterocyclic carbene complex Ru(IMes

) is an efficient catalyst for both direct hydrogenation and transfer hydrogenation of ketones and imines, in the absence of base.

Four ruthenium-N-heterocyclic carbene complexes (3-6) have been prepared and the new compounds characterized by C, H, N analyses, 1 H-NMR and 13 C-NMR. The reduction of ketones to alcohols via transfer hydrogenation was achieved with catalytic amounts of complexes 3-6 in the presence of t-BuOK.

## Abstract A library of organometallic compounds derived from primary and secondary amines cyclometalated by ruthenium(II), rhodium(III) and iridi‐ um(III) was tested in the asymmetric transfer hydrogenation of a number of ketones and imines. All compounds displayed high catalytic activity for the
