| Abstract | Abstract Three non-crosslinked polymers are used as supports for rhodium complexes, viz ., . The two polystyrenes are flexible, whereas the poly(iminomethylene) has a rigid rod configuration. Rhodium is anchored by addition of either [RhCl(C 2 H 4 ) 2 ] 2 or [RhCl(1,5-cyclooctadiene)] 2 . These systems are investigated for catalytic activity in the hydrogenation of cyclohexene with moleclar hydrogen. For comparison, rhodium complexes of PPh 3 and of PCy 2 Ph are studied under the same conditions, i.e. , in THF at 30 °C and a constant hydrogen pressure of 1 atm. The polymer catalysts are more stable than the corresponding monomers and they have a higher activity. The latter is ascribed to a diminished tendency to dimerize. In contrast to the monomers, the polymer systems are also active in the hydrogenation of 1,5-cyclooctadiene. |
