ResumoCarbonyl sulfide, carbon disulfide and carbon dioxide interact with transition metal complexes to form complexes with a number of transition metals and undergo a variety of chemical transformations including insertion, dimerization, disproportionation, coupling and catalytic reactions. The coordination chemistry of these closely related molecules is very diverse. The metal-(η2-CS2) complexes are much more stable than the metal-(η2-COS) and metal-(η2-CO2) complexes. Elimination of sulfur from the metal-(η2-COS) complexes is more facile. Carbon dioxide undergoes coupling reactions with unsaturated organic compounds on transition metal centers to produce metallocycles. The reduction of carbon dioxide catalyzed by transition metal complexes, using different methods, is discussed.
