Abstract

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