Ein stabiler, bemerkenswert aktiver, wasserlöslicher Pd-Katalysator zur alternierenden Copolymerisation von Ethen und CO in Wasser

Abstract: Alternierende Copolymere aus Olefinen und CO sind relativ neue, kostengünstige Materialien mit interessanten physikalischen Eigenschaften. [1] Die Entdeckung von aktiven kationischen Palladiumkatalysatoren mit flexiblen cis-chelatisierenden Diphosphanen hat eine kommerzielle Herstellung solcher Polymere ermöglicht. [2] Insbesondere Katalysatorsysteme, die in situ mit einer Pd-Katalysatorvorstufe, einem sterisch anspruchsvollem Diphosphan wie 1,3-Bis[di(2-methoxyphenyl)phosphanyl]propan (D-o-APPr) und einem Übe… Show more

“…With catalysts, the microstructure of the resulting polymers can be adjusted 15–20. In addition, water is a perfect solvent for fabricating many types of polymers as indicated in the literature 21–24. The development of water‐soluble catalysts started with the modification of the well known ligand 1,3‐bis(diphenylphosphino)propane (dppp) by introduction of hydrophilic sulfonate functional groups into the lipophilic part.…”

“…[15][16][17][18][19][20] In addition, water is a perfect solvent for fabricating many types of polymers as indicated in the literature. [21][22][23][24] The development of water-soluble catalysts started with the modification of the well known ligand 1,3-bis(diphenylphosphino)propane (dppp) by introduction of hydrophilic sulfonate functional groups into the lipophilic part. Another approach is the attachment of hydrophilic hydroxyalkyl groups to the phosphorus atoms in dppp.…”

“…Hence, the reaction of cyanoacetylenic alcohols with secondary phosphines, that proceeds regio-and stereoselectively under mild conditions as trans addition of nucleophiles (specifically, P-nucleophiles [3,13]) to activated acetylenes [14], opens up a convenient and effective synthetic route to new functionalyzed tertiary phosphines, promising polydentate amphiphilic ligands for the design of catalysts of new generation [15,16], as well as highly reactive intermediates for fine organic synthesis.…”
