Rhodium, " titanium,and tungsten " complexes have also been used for this reaction. The reaction can be promoted photochemically and the rate is enhanced by the presence of primary amines.Coordinating ligands also accelerate the reaction,polymer-supported promoters have been developed " and there are many possible variations in reaction conditions.The Pauson-Khand reaction has been done under heterogeneous reaction conditions, and with... 

Pauson-Khand reaction. Cobalt is deposited by decomposing dicobalt octacarbonyl in refluxing toluene in the presence of mesoporous silica. The substance is active as a heterogeneous catalyst for the Pauson-Khand reaction. A related catalyst is cobalt-on-carbon, which can be used at least 10 times with yields maintaining at the 95% level. ...
