Cobalt Salts-Catalyzed Carbonylation of Aromatic Halides under Photostimulation

Article abstract of DOI:10.1246/cl.1987.577

A novel method for the carbonylation of aromatic halides by the cobalt salt catalysts such as Co(OAc)2*4H2O, CoCl2*6H2O, CoSO4*7H2O, Co(OH)2, Co(OH)3, CoO, and Co2O3 was investigated in an aqueous alkaline solution under photostimulation.These salts were found to have a catalytic activity as high as that of Co2(CO)8 under mild conditions.
