Description

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.
