Liquid Phase Carbonylation with Solid Catalyst. Carboxy Methylation of Dihalo Methane with Group VIII Metals Supported on Active Carbon

It was found that cobalt supported on active carbon showed an excellent catalytic activity for the carbonylation of dibromo methane in the liquid phase. For example, when the reaction was conducted under the conditions of 140 °C, P(CO) = 31 atm, the yields of dimethyl malonate and bromomethyl acetate were 34.4% and 22.2%, respectively. Pd and Rh also showed catalytic activities.
