An aromatic carbonate process comprising contacting a phenol, carbon monoxide in the presence of a base, Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium or platinum having an oxidation state greater than zero. The resulting aromatic mono- and polycarbonates are useful in the preparation of polycarbonates or as polycarbonates, per se, respectively, which can be molded or formed into films, sheets, fibers, laminates or reinforced plastics by conventional techniques.
