Abstract: A process can be used 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 a lipophilic carboxylate ligand. After completion of the reaction, the catalyst is separated from the cyclic carbonate by the use of two organic solvents of different polarity and having a miscibility gap. The silver catalyst is enriched in the less polar solvent and the cyclic carbonate in the more polar solvent.

Abstract: A method of preparing an ester by reacting a carboxylic acid with a (C1-C36)alcohol in the presence of a catalyst that is suitable for preparing carboxylic acid esters of monomeric carboxylic acids in high yield. The method reduces by-products of the reaction, in particular esters of dimeric, trimeric and/or oligomeric carboxylic acids. The method requires a minimal excess of alcohol and does not require removal of water and/or carboxylic acid ester from the reaction mixture. The method is particularly suitable for the reaction of hydroxyalkylcarboxylic acids and fatty alcohols.
