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.</dcterms:abstract> <dcterms:title>Hydroformylation with Dendritic-Polymer-Stabilized Rhodium Colloids as Catalyst Precursors</dcterms:title> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:15:25Z</dc:date> <dc:contributor>Mecking, Stefan</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9935"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:15:25Z</dcterms:available> <dc:rights>deposit-license</dc:rights> <dcterms:issued>2007</dcterms:issued> <dc:creator>Mecking, Stefan</dc:creator> </rdf:Description> </rdf:RDF>
