Back Cover: Hydroformylation of Olefins by a Rhodium Single-Atom Catalyst with Activity Comparable to RhCl(PPh3 )3 (Angew. Chem. Int. Ed. 52/2016)

Somewhere over the rainbow single-atom catalysts dispersed on a support surface offer a tantalizing bridge between homogeneous and heterogeneous catalysts. In their Communication on page 16054 ff., B. Qiao, T. Zhang, and co-workers describe rhodium single-atom catalysts supported on ZnO nanowires that show an olefin hydroformylation efficiency comparable to that of homogeneous Wilkinson's catalyst.
