Disclosed are cationic ruthenium arene complexes of Formula (I): [Ru(D-Z1-NHR1)(Ar)(LB)n]r+[Y-]r wherein Ar is optionally substituted aryl, D-Z1-NHR1 is a coordinated bidentate ligand wherein D, Z1, R1 and R2 are as defined herein, and where R1 and Ar, or R2 and Ar may be linked together, n is 0 or 1, r is 1 or 2, LB is a neutral Lewis base, and Y is a non-coordinating anion. The complexes are active catalysts for reduction reactions, including the transfer-hydrogenation of carbon-oxygen (C=O) and carbon-nitrogen (C=N) double bonds.
