Polymer-Supported Haloarene Chromium Dicarbonyl Isonitrile

Different arene Cr(CO)3 complexes were supported on a polystyrene isonitrile resin by photochemical promoted replacement of a chromium carbonyl ligand by the NC group. The supported complexes proved to be stable and were successfully used for further transformations. In particular, the reactivity of dichlorobenzene complexes to different nucleophiles was investigated and found to be comparable with that of the parent Cr(CO)3 complexes.
