摘要：

(Chemical Equation Presented) Pressure-sized clusters: Aqueous solutions of rhodium complexes stabilized by phosphinophosphonic acid ligands turn ink-black under a hydrogen atmosphere. Depending on the hydrogen pressure applied, rhodium clusters of 2-6 nm can be isolated (see scheme). These clusters are catalysts for the biphasic hydrogenation of olefins, arenes, and nitro compounds. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
