Abstract
Description
Die Erfindung betrifft die chemische Verbindungsgruppe der wasserlöslichen chiralen und achiralen Phosphine, Verfahren zu ihrer Herstellung und deren Verwendung.The invention relates to the chemical connecting group of water-soluble chiral and achiral phosphines, process for their preparation and their use.
Bekannt wurde die Synthese von meta-Sulfophenyl-diphenylphosphin durch die Veröffent lichung von Ahrland und Mitarbeitern (J. Chem. Soc. 1958, 276). Durch Änderung der Säurekonzentration und des Lösungsmittels wurde es möglich, mehrfachsulfonierte Triphenylphosphine herzustellen (FR-PS 23 14 910). Entsprechend dieser Methode lassen sich Tris-(ω-phenylalkyl)-phosphine unter Verwendung von Schwefeltrioxid-Oleum synthetisieren (Toth et al., Organometallics 1993, 12, 164).The synthesis of meta-sulfophenyl-diphenylphosphine became known by the public of Ahrland and co-workers (J. Chem. Soc. 1958, 276). By changing the Acid concentration and the solvent became multi-sulfonated To produce triphenylphosphines (FR-PS 23 14 910). According to this method can be Synthesize tris (ω-phenylalkyl) phosphines using sulfur trioxide oleum (Toth et al., Organometallics 1993, 12, 164).
Von mehreren Arbeitskreisen wurden unterschiedliche chirale Phosphine nach dem Oleumverfahren in wasserlösliche Liganden überführt. Diese Phosphor-Sulfo-Verbindungen wurden im wäßrigen Milieu in Komplexkatalysen eingesetzt (Sinou et al., Organometallics 1989, 8, 542; EP-PS 0 491 240).Different chiral phosphines after the Oleum process converted into water-soluble ligands. These phosphor-sulfo compounds were used in an aqueous environment in complex catalysts (Sinou et al., Organometallics 1989, 8, 542; EP-PS 0 491 240).
Die Ringöffnung von Sultonen bietet eine weitere Möglichkeit zu wasserlöslichen Phosphinen zu gelangen (Oehme et al., J. prakt. Chem. 1987, 329, 725; Z. Chem. 1989, 29, 447). B. Fell und Mitarbeiter nutzten die Sulfonalkylringe von Tris-(2-pyridyl)-phosphin mit C₃- bis C₁₄- Alkansultonen zur Herstellung von wasserlöslichen Komplexliganden (J. Mol. Catal. 1991, 66, 143).The ring opening of sultons offers another possibility for water-soluble phosphines to arrive (Oehme et al., J. Prakt. Chem. 1987, 329, 725; Z. Chem. 1989, 29, 447). B. fur and co-workers used the sulfonalkyl rings of tris- (2-pyridyl) -phosphine with C₃- to C₁₄- Alkane sultones for the preparation of water-soluble complex ligands (J. Mol. Catal. 1991, 66, 143).
Sulfobenzoesäureanhydrid wurde zur Herstellung von wasserlöslichen Bis-(diphenylphos phinoethyl-(1,2)-amino-2-benzyl-sulfonsäure genutzt (Whitesides et al., J. Org. Chem. 1981, 46, 2861). Stelzer und Mitarbeiter stellten aus hoch giftigem Phosphorwasserstoff und p- Fluorphenykaliumsulfonat das Tri-(p-phenyl-kalium-sulfonato)-phosphin her. Dieser auf den ersten Blick einfache Syntheseweg beinhaltet neben der hohen Toxizität von PH₃ auch noch die Abtrennung von Kaliumchlorid als einen erheblichen Nachteil (Angew. Chem. 1993, 105, 1097).Sulfobenzoic anhydride has been used to prepare water-soluble bis (diphenylphos phinoethyl- (1,2) -amino-2-benzyl-sulfonic acid used (Whitesides et al., J. Org. Chem. 1981, 46, 2861). Stelzer and co-workers made from highly toxic phosphine and p- Fluorophenykaliumsulfonat the tri (p-phenyl-potassium-sulfonato) phosphine. This on the first look simple synthetic route includes in addition to the high toxicity of PH₃ also the separation of potassium chloride as a considerable disadvantage (Angew. Chem. 1993, 105, 1097).
Alle diese Verfahren zur Herstellung von wasserlöslichen Sulfophosphinen und -diphosphinen beruhen auf der Substitution von einem oder mehreren Wasserstoffatomen. Die Substitution wird überwiegend an aromatischen Ringen durch Sulfogruppen vorgenommen.All of these processes for the preparation of water-soluble sulfophosphines and diphosphines are based on the substitution of one or more hydrogen atoms. The substitution is mainly carried out on aromatic rings by sulfo groups.
Des weiteren ist die Addition von n-Mercaptobutan an 1,1-Bis-(diphenylphosphino)-ethen bekannt geworden, die jedoch nur in Lösung zu einem Addukt führt, wie es mittels NMR- Spektroskopie postuliert werden kann (A. M. Herring et al., J. Chem. Soc., Chem. Commun. 1986, 882; S. J. Higgins und B. L. Shaw, J. Chem. Soc. Dalton Trans. 1989, 1527). Unter UV-Bestrahlung in einer photolytischen Reaktion gelang die Synthese zwischen Diphenylvinylphosphin und Thiolen in 19 bis 65 Stunden (D. H. Brown et al., J. Chem. Soc. Dalton Trans. 1976, 334). Furthermore, the addition of n-mercaptobutane to 1,1-bis (diphenylphosphino) ethene become known, which, however, only leads to an adduct in solution, as is Spectroscopy can be postulated (A.M. Herring et al., J. Chem. Soc., Chem. Commun. 1986, 882; S. J. Higgins and B. L. Shaw, J. Chem. Soc. Dalton Trans. 1989, 1527). Under UV radiation in a photolytic reaction succeeded in the synthesis between Diphenylvinylphosphine and thiols in 19 to 65 hours (D.H. Brown et al., J. Chem. Soc. Dalton Trans. 1976, 334).
Ferner wurden Michael-Additionen an Bis(diphenylphosphino)-ethen mit einer Reihe von Substanzklassen vorgenommen. Dabei sind sowohl reine Phosphine als auch Übergangsmetall komplexe genutzt worden.

Der Einsatz von optisch aktiven Verbindungen von Shaw (1986) und Brunner (1991) soll hervorgehoben werden.The use of optically active compounds by Shaw (1986) and Brunner (1991) is said to be be highlighted.
Alle diese Reaktionen wurden in hydrophoben Medien, wie Dichlormethan, Chloroform und Toluen, ausgeführt. Das Ziel der Umsetzungen waren neue, rein organische Verbindungen. Die auf diese Weise erhaltenen Verbindungen werden insbesondere als Liganden für Komplexe in katalytischen Reaktionen verwendet. So wurden Komplexverbindungen von sulfongruppen haltigen Triphenylphosphinderivaten mit Metallen der VIII. Nebengruppe erfolgreich in katalytischen Systemen eingesetzt, beispielsweise bei Hydroformylierungen unter Anwendung von Rhodium-Sulfotriphenylphosphinkomplexen. In diesen Mehrphasenreaktionen wird das Problem der Katalysatorrückgewinnung durch einfache Phasentrennung gelöst. Die Sulfo phosphine werden durch die vorher bekannte Umsetzung von Triphenylphosphin mit Schwefel trioxid-Oleum gewonnen. Prinzipiell treten bei der genannten Verfahrensweise immer Produkt gemische auf. Die Aufarbeitung und die Isolierung der Sulfophosphine von den ent sprechenden Phosphinoxiden und -sulfiden sind kostenintensive Prozeduren. Die Reindar stellung spezieller Produkte erfordert aufwendige Trennoperationen.All of these reactions were carried out in hydrophobic media such as dichloromethane, chloroform and Toluen, executed. The aim of the implementations were new, purely organic compounds. The Compounds obtained in this way are used in particular as ligands for complexes in used catalytic reactions. So were complex compounds of sulfone groups containing triphenylphosphine derivatives with metals of subgroup VIII successfully in catalytic systems used, for example in hydroformylation using of rhodium-sulfotriphenylphosphine complexes. In these multi-phase reactions, that is Catalyst recovery problem solved by simple phase separation. The sulfo Phosphines are made by the previously known reaction of triphenylphosphine with sulfur trioxide oleum won. In principle, product always occurs in the procedure mentioned mix up. The processing and isolation of the sulfophosphines from the ent Talking phosphine oxides and sulfides are costly procedures. The Reindar The provision of special products requires complex separation operations.

1,1 mmol 2-(3-Natriumsulfonatopropylthio)-ethyldiphenylphosphin und Dikaliumtetrachlor
palladium wurden in je 2 ml Wasser gelöst und zusammengegeben. Es ergibt sich eine dunkle
Lösung, die für zwei Stunden bei Raumtemperatur gerührt wurde. Das Wasser wurde
eingeengt und mit Methanol ein gelber Niederschlag ausgefällt.
