dc.description.abstractNew supported rhodium(I) catalyst precursors were obtained in reaction of [Rh(OMe)(cod)]<sub>2</sub> with polymeric monoliths containing methyl-imidazolium moieties and applied in 1-hexene hydroformylation at 10 atm of CO/H<sub>2</sub>. Under solventless conditions with a small amount of P(OPh)<sub>3</sub> as a modifying ligand, [P(OPh)<sub>3</sub>]/[Rh] = 2, ca. 80% of aldehydes with a high n/iso ratio of ca. 6 was obtained in eight successive runs. When P(OCH<sub>2</sub>CF<sub>3</sub>)<sub>3</sub> was used instead of P(OPh)<sub>3</sub>, n/iso ratios up to 49.8 were obtained, however, the systems were active only in two subsequent reactions. With PPh<sub>3</sub> as a modifying ligand, the yield of aldehydes decreased to ca. 20% already in the third run and n/iso was ca. 3. © 2009 Elsevier B.V. All rights reserved.
