Alternative supported aqueous-phase catalyst systems

摘要: Abstract The concept of supported aqueous-phase (SAP) catalysis has been extended to olefin hydroformylations by the use in situ formed Rh-, PtSnCl 3 - and Co-complexes containing HexDPPDS, TAPTS TPrPTS as ligands, respectively. (HexDPPDS = hexyl-bis(sodium- m -sulfonatophenyl)phosphine; tris(ω-(sodium- p -sulfonatophenyl)alkyl)phosphines, where alkyl CH 2 , TBeTS; C H 4 TEtPTS, 6 TPrPTs). Furthermore, some data are reported on SAP asymmetric hydroformylation styrene PtCl [( S,S )-BDPP-(( -NMe )(BF )) ] + SnCl system hydrogenation dehydro-phenylalanine derivatives with Rh(COD)[( )-BDPP-( -NME ) ](BF 5 )-Chiraphos-( complexes. (BDPP 2,4-bis(diphenylphosphino)pentane; Chiraphos 2,3-bis(diphenylphosphino)butane). For sake comparison, two-phase catalytic results also given each alternative applications, well appropriate (organic) homogeneous values, which were obtained analogous complexes respective non-funtionalized ligands. With exception Co-system, systems show similar selectivity only non-aqueous catalysts. anomalous behavior Co-system presence water is attributed sulfonate groups ligand may interact cobalt.
