Zusammenfassung

Hydroformylation of 1-hexene with rhodium colloids stabilized by poly(ethylene imine)amides with a hyperbranched polyamine core and a lipophilic periphery is reported. The catalyst selectivity for aldehydes increases with increasing temperature or pressure. The ratio of linear to branched aldehydes decreases with increasing temperature. At 80°C and 90 atm, 1-hexene is converted completely with 96% selectivity for aldehydes, with a ratio of linear/ branched aldehydes of 58:42. Turnover numbers up to 3X10000 (calculated with respect to the entire amount of Rh present) were observed. The results indicate that the catalyst precursor colloids serve as a reservoir for the formation of soluble Rh(I) complexes as the active species.
