Key words: ionic phosphite, hydroformylation, supercritical carbon dioxide, ionic liquids, rhodium
A new method for the preparation of ionic phosphite ligands is developed. The first example of the use of this type of ligands in the hydroformylation catalyzed by rhodium complexes in organic solvents, ionic liquid and supercritical carbone dioxide is described. It is shown that the hydroformylation reaction in biphasic mixtures «ionic liquid/supercritical carbon dioxide» leads to a higher activity of the catalyst.
