Abstract
U okviru disertacije opisani su rezultati istraživanja reakcija okso vrsta molibdena(VI) i vanadija(IV) s derivatima salicilaldehida i L-asparaginske kiseline, D,L-asparagina, L-glutamina te L-ornitina. Opažena je i opisana katalitička uloga izoliranih oksomolibdatnih i oksovanadatnih vrsta u oksidativnoj dekarboksilaciji asparagina pri čemu dolazi do nastanka kumarin-3-karboksamida i dekavanadata, odnosno kompleksa [Mo2O4(C11H10N2O3)2], dok je u reakciji s glutaminom izoliran sukcinamid odnosno kompleks [VO(C12H12N2O4)(OC2H5)(HOC2H5)]. U reakciji s L-ornitinom nastao je diimin i došlo je zatvaranja piperidinskog prstena i koordinacije nastalog diimin na [MoO2]2+ kationsku vrstu. Opisana je uloga aminokiselina u reakcijama nastajanja molibdovanadatnih poliokso vrsta. Pripravljeni su i opisani tetranuklearni molibdovanadatni kompleks [Mo2V2O9(C11H8NO5)2]2– s derivatom salicilaldehida i L-aspartata, molibdatni anion Lindquistovog tipa, [MoVMo5 VIO19]3-, oktamolibdati [Mo4O13(NH4)Mo4O13]n i [Mo4O13(H3O)Mo4O13]n te molibdati i molibdovanadati, Kegginovog [BrMoV xMoVI (12-x)O44]n-, odnosno super-Kegginovog tipa [BrMoV xMoVI 13-xVIV 5VV (5-x)O62]n-. Pripravljeni spojevi su identificirani na osnovi rezultata kemijske analize, spektroskopskih metoda, termičkih metoda (termogravimetrija i diferencijalna pretražna kalorimetrija) te difrakcije rentgenskih zraka na polikristalnom i monokristalnom uzorku.
Abstract (english)
The reaction results of oxo molybdenum(VI) and vanadium(IV) species with salicylaldehidato amino acids (L-aspartatic acid, D,L-asparagine, L-glutamine and L-ornithine) derivatives are described in the thesis. In the reactions of molybdenum(VI) or vanadium(IV) with D,L-asparagine derivatives, the coumarine-3-carboxamide, decavanadate and [Mo2O4(C11H10N2O3)2] were obtained. Succinamide was obtained from the reactions with L-glutamine and dioxomolybdenum(VI), while with vanadylsulfate mononuclear [VO(C12H12N2O4)(OC2H5)(HOC2H5)] complex was obtained. The dioxomolybdenum(VI) complex with piperidine derivative was observed due to the diimine formation when L-ornithine was used. Molybdovanadate reactions resulted in tetranuclear mixed complex formation with aspartate derivative and Lindquist type molybdate [MoVMo5 VIO19]3-. Octa- [Mo4O13(NH4)Mo4O13]n i [Mo4O13(H3O)Mo4O13]n . Keggin type molybdate [BrMoV xMoVI (12-x)O44]n– and super-Keggin molybdovanadate [BrMoV xMoVI 13-xVIV 5VV (5-x)O62]n– were observed and characterized. Prepared compounds were identified and characterized by means of chemical and thermogravimetric analysis in combination with differential scanning calorimetry, spectroscopy methods, X-ray diffraction on monocrystalline and polycrystalline samples where applicable.
