RD-10,733 ABSTRACT OF THE DISCLOSURE A carbonylation process which comprises contacting a .beta.-fluoralkanol with carbon monoxide and a Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium,or platinum having an oxidation state greater than zero. The resulting .beta.-fluoroaliphatic carbonates can be employed in combination with alkanols and/or phenols to prepare aliphatic and aromatic mono- and polycarbonates. The resulting carbonates are useful in a wide variety of applications, especially polycarbonates which can be molded or formed into films, sheets, fibers, laminates, or reinforced plastics by conventional techniques.
