Process for the preparation of symmetrical and asymmetrical carbonates of the general formula I by reaction of alcohols of the general formula II and alkyl or aryl halides of the general formula III,R—OH??IIR′—HAL??IIIwith carbon dioxide and caesium carbonate at room temperature in dipolar aprotic solvents.

Carbonates could be obtained by enzymatic alkoxycarbonylation from vinyl carbonates, which are easily prepared from vinyl chloroformate. The reaction was catalyzed by Candida antarctica lipases, SP 435 and SP 435 A. The method could be also used for the synthesis of carbamates. When racemic alcohols were used, lipase catalyzed their resolution, and chiral carbonates were obtained with different enantiomeric excesses depending upon the structure of the alcohol.
