Transition metal nanoparticles have attracted a great deal of attention. This review discusses the synthesis of heterobimetallic cobalt-rhodium nanoparticles and their use as catalysts in organic transformations. Co-Rh nanoparticles (Co2Rh2) with a fixed stoichiometry (2 : 2) were easily obtained from Co2Rh2(CO)12. These nanoparticles were quite effective catalysts for carbonylation reactions. Particularly, special focus is paid to the Pauson-Khand-type reaction.
