A process can be used for preparing cyclic carbonates with an exocyclic vinylidene group by reacting a propargylic alcohol with COin 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.

Process for preparing cyclic carbonates with an exocyclic vinylidene group

The invention relates to a process for the preparation of acetals from carbon dioxide. The invention also relates to a mixture of phosphorus containing ligands comprising least one polydentate ligand and at least one monodentate ligand. Further, the invention also relates to the use of mixtures comprising at least one polydentate ligand and at least one monodentate ligand in transition metal complexes for the preparation of acetals.

Process for the production of acetals from carbon dioxide

A process to produce N-vinyl compounds by homogeneous catalysis can be performed. Acetylene is reacted with a compound having at least one nitrogen bearing a substitutable hydrogen residue in a liquid phase in the presence of at least one phosphine as a catalyst to produce the compounds.
