Zusammenfassung: | Transition metal complex catalyst for heterogeneous catalysis comprises: (1) a mixed polymer salt consisting of a transition metal complex; (2) a surface active compound comprising an alkyl chain having an ionic anchor group; and (3) a soluble ionic polymer material comprising ionic groups on a neutral polymer or is a homopolymer of an ionic monomer or copolymer or block polymer of ionic and neutral monomers. Transition metal complex catalyst (I) for heterogeneous catalysis, comprises: (1) a mixed polymer salt consisting of a transition metal complex of formula, XQ-nM((D-)iY(-A)j)n (1); (2) a surface active compound comprising an alkyl chain having an ionic anchor group of formula, Z-C (2) whereby the ionic group is capable of forming an ionic group to an ionic polymer material; and (3) a soluble ionic polymer material comprising ionic groups on a neutral polymer or is a homopolymer of an ionic monomer or copolymer or block polymer of ionic and neutral monomers. M = Ti, V, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au; X = group containing C, N, P, O or halogen or S capable of forming a covalent or coordinating group to M; D = N, P, O or S containing donor group capable forming a coordinating bond to M and Y; Y = alkyl, alkylphenyl, aryl or heteroaryl, optionally substituted; A = cationic or anionic anchor group capable of forming an ionic bond to an ionic polymer; Q = 1-8; n = 1-2; i, j = 1-4; Z = CH3-(CH2)p; p = 6-18; and C = cationic or anionic anchor group. An Independent claim is also included for a process for the preparation of transition metal complex catalysts (I) by heterogenation of transition metal complexes by addition of a solution of an ionic surface active compound to a homogeneous phase of a preformed transition metal complex compound of a transition metal compound and ligands to dissolve an ionic polymer to form a mixed polymer salt, optionally followed by drying.
Die Erfindung betrifft feste heterogenisierte Katalysatoren und ihre Verwendung in katalytischen Reaktionen in der Flüssigphase. Die Katalysatoren werden aus Übergangsmetallkomplexen, ionischen oberflächenaktiven Verbindungen sowie ionischen Polymeren gebildet, die in der Kombination als gemischtes polymeres Salz Katalysatoren mit verringertem Leaching, verbesserter Aktivität und Selektivität sowie heterogenisierte chirale Übergangsmetallkomplex-Katalysatoren ergeben. Die Herstellung erfolgt, indem die Lösungen eines Übergangsmetallkomplexes und eines ionischen p |
