摘要
Rh(acetylacetonate)(CO)(2)/sulfonated-Xantphos dissolved in pure 1-n-butyl-3-methylimidazolium hexafluorophosphate ionic liquid catalyses the hydroformylation of heavy olefins (C-8-C-12) with selectivities (up to 99% in n-aldehydes). The selectivity is strongly influenced by the nature of the ionic phase and co-solvent.
