[GRAPHICS]Dispersions of nanometer-sized cobalt particles with very high stability were prepared in charcoal and analyzed by electron microscopy and X-ray analysis. The resulting cobalt nanoparticles on charcoal (CNC) were successfully used as a catalyst for the carbonylative cycloaddition of alkyne, alkene, and carbon monoxide (Pauson-Khand reaction), hydrogenation, and the reductive Pauson-Khand reaction.

A new Pauson-Khand catalyst based on colloidal cobalt nanoparticles has been developed; the catalyst is highly effective for many intra- and inter-molecular Pauson-Khand reactions and can be recycled and reused many times without losing catalytic activity.
