1_1-2/2008Cover Picture: A Versatile Iridium Catalyst for Aldehyde Reduction in Water (ChemSusChem 1-2/2008)

The cover picture shows a reaction scheme for the iridium-catalyzed chemoselective reduction of aldehydes in water, set against a background of clear waters on an unspoilt beach. Catalysis in water is attracting increasing attention in response to calls for environmentally benign and efficient chemical processes. In their Communication on page 71 ff., J. Xiao et al. describe how Ir-N-tosyldiamine complexes, previously shown to be excellent catalysts for the transfer hydrogenation of aldehydes in water, also catalyze the reduction of a wide range of aldehydes, including aromatic, aliphatic, heterocyclic, and α,β-unsaturated aldehydes, in water. The hydrogenation reaction is efficient and chemoselective and proceeds without the need for added organic co-solvents, thus providing an atom-economic and environmentally benign means for aldehyde reduction.
