Application

  • Cobalt carbonyl [Co2(CO)8] is commonly used as a catalyst in the hydroformylation (oxo reaction) of alkenes.
  • Along with pyridine, it can be used as a catalyst in the carboxylation of alkenes into corresponding acids and esters.
  • It is employed as a key precursor in the preparation of cobalt platinum (CoPt3), cobalt sulfide (Co3S4) and cobalt selenide (CoSe2) nanocrystals.
  • It is also used as a reagent in Pauson-Khand cyclizations and Nicholas reaction.
