Abstract: The present invention relates to a process for preparing cyclic carbonates with an exocyclic vinylidene group by reacting a propargylic alcohol with CO2 in the presence of a silver catalyst having at least one bulky ligand and a lipophilic carboxylate ligand, where after completion of the reaction the catalyst is separated from the cyclic carbonate by the use two organic solvents of different polarity and having a miscibility gap, where the silver catalyst is enriched in the less polar solvent and the cyclic carbonate in the more polar solvent.
