Cobalt complexes thiocarbonyls

Liganded cobalt complexes react with carbon disulfide by addition across one of the C=S bonds to give relatively stable complexes 10. The same complex reacts with carbonyl sulfide to give a liganded carbonyl complex 11 andMesPS. In the reaction of carbon sulfose-lenide at -20 °C the adduct 12 as well as the thiocarbonyl complex 13 are formed, indicating that carbon sulfoselenide can be used for the synthesis of thiocarbonyl compounds.
