Isobutene hydroformylation in catalytic systems based on rhodium compoundsand polyelectrolytes

The catalytic properties of water-soluble systems based on rhodium complexe s and polyelectrolytes in isobutene hydroformylation were studied. All of t he catalytic systems exhibited an unexpectedly high activity under the cond itions where homogeneous hydroformylation virtually did not occur in the pr esence of conventional rhodium catalysts. A stable catalytic system based o n acacRh(CO)(2)-PEG complex was proposed, allowing isobutene hydroformylati on to be performed with a high activity under mild conditions.
