Structural Interconversion of Bimetallic Carbonyl Clusters ­Induced by a NHC Ligand and Its Selectivity on Fragments

The reactions of IMes-HCl with bimetallic iron-copper clusters were investigated and it showed that interconversions among bimetallic FexCuy(CO)zn– clusters were induced by IMes-HCl. The reaction priority of IMes-HCl with fragments in FexCuy(CO)zn– was also investigated and the reaction behaviors of zero valent Fe(CO)4 and divalent Fe(CO)4 with IMes-HCl were discussed.
