Chelating bis-carbene rhodium(iii) complexes in transfer hydrogenation of ketones and iminesElectronic supplementary information (ESI) available: spectroscopic data for the rhodium(iii) complexes. See http://www.rsc.org/suppdata/cc/b1/b109491b/

Abstract
Chelating rhodium(III) carbene complexes are accessible via a simple synthesis and are catalytically active for hydrogen transfer from alcohols to ketones and imines.
