Inside Cover: A General and Efficient Iridium-Catalyzed Hydroformylation of Olefins (Angew. Chem. Int. Ed. 1/2011)
With respect to scale, hydroformylation of aliphatic olefins is the most important homogeneous catalytic reaction. More than 8 million tons of oxo products are annually produced by this method. In their Communication on page 280 ff., Beller and co-workers report on a general protocol for the catalytic hydroformylation of olefins using Ir precursors and phosphine ligands. By carefully controlling the conditions, unwanted hydrogenation side reactions are prevented.
