Cobalt–rhodium heterobimetallic nanoparticle-catalyzed reactions

Abstract

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.
