The thermal decomposition of [Ru 3 (CO) 12 ] allowed the production of ruthenium nanoparticles (NPs) with a unique activity for this metal in the hydrogenation of aliphatic nitriles, yielding the corresponding tertiary amines (selectivity 80%) and aromatic nitriles to secondary amines and imines at 140 °C, employing a moderate hydrogen pressure. The use of several stabilizing agents such as sodium dodecylsulfate and sodium 2‐ethylhexanoate allowed the stabilization of ruthenium NPs (Ru‐NPs), and further reactivity in the hydrogenation process was assessed. The Ru‐NPs were characterized by transmission electron microscopy and exhibited an average size of 2–3 nm. Copyright © 2012 John Wiley & Sons, Ltd.
