20.500.12556/RUL-160975 Sinteza in uporaba iridijevih katalizatorjev za izotopsko izmenjavo vodika na osnovi dendrimernih nosilcev The synthesis and application of dendrimer-supported iridium catalysts for hydrogen isotope exchange V sklopu magistrskega dela smo s preoblikovanjem fosfinskega liganda Kerrovega tipa katalizatorja pripravili štiri različne iridijeve komplekse za izotopsko izmenjavo vodika. Glavni cilj je bil pritrditi kompleks na dendrimerne nosilce preko amidne vezi. Pripravljene iridijeve zvrsti smo preizkusili v modelni reakciji, devteriranju acetofenona, in rezultate primerjali z učinkovitostjo komercialno dostopnega Kerrovega katalizatorja. Ugotovili smo, da so sintetizirani iridijevi kompleksi primerljivo aktivni kot izvirna spojina. Preverili smo tudi možnost ponovne uporabe katalizatorjev po končani reakciji. V ta namen smo z NMR eksperimentom preučevali porazdeljevanje funkcionaliziranih poli(propilen imin) (PPI) dendrimerov med organsko in vodno fazo. In the scope of the master’s thesis, four unique iridium catalysts for hydrogen isotope exchange were prepared by modifying the phosphine ligand of the Kerr’s type catalyst. Attaching the latter complex to dendrimer supports via an amide linkage was of particular interest. The synthesised iridium species were tested in a model reaction, deuteration of acetophenone. The obtained results were compared to the activity of the commercially available catalyst. It was found that the activity of prepared iridium complexes was comparable to the parent catalyst. Upon completion of the reaction, recycling of the catalytic species was investigated as well. In a series of NMR experiments, the distribution of functionalised poly(propylene imine) (PPI) dendrimers between organic and aqueous layers was also examined. izotopska izmenjava vodika iridij obnovljivi katalizatorji trajnostna kemija hydrogen isotope exchange iridium recyclable catalyst sustainable chemistry true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-09-06 07:50:00 2024-09-06 07:50:02 2024-10-25 09:56:15 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 22806 212935427 Hofferle_Jakob_-_Sinteza_in_uporaba_Kerrovih_katalizatorjev_na_osnovi_dendrimernih_nosilcev.pdf Hofferle_Jakob_-_Sinteza_in_uporaba_Kerrovih_katalizatorjev_na_osnovi_dendrimernih_nosilcev.pdf 1 B481F0810AEF2A3EF983F5819DCE870A ef9657460d7e947fb5e2a9e2cc80a186a0921ca0848a9c01e73ac76a6b06e465 d765d907-6c13-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189808 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
