Study of derivatization reactions for ESI-MS analysis of hardly ionizable rhenium aryl chlorocomplexes
Vlk, Mikuláš ; Štícha, Martin (advisor) ; Kozlík, Petr (referee)
Mass spectrometry with electrospray ionization is an excellent method for structural analysis of coordination compounds with outstanding sensitivity and selectivity. However, it fails to detect some low-polar rhenium complexes. This master thesis describes derivatization method of non-ionizable rhenium complexes with 1,2-dihydroxybenzene and 2,3- dihydroxytoluenene. Fragmentation mechanisms and structure of prepared complexes was studied using high resolution mass spectrometry and collision-induced dissociation (CID). Furthermore, density functional theory (DFT) computational method was used for prediction of bond cleavage based on bond lengthening.

MS Characterization of Rhenium complexes
Vlk, Mikuláš ; Štícha, Martin (advisor) ; Kozlík, Petr (referee)
Ideal radiochemical properties make rhenium complexes coordinated with suitable organic ligands relevant for use in nuclear medicine. They find a wide range of uses as diagnostic and palliative agents. However, detailed characterization and availability of suitable analytical methods is needed for use in clinical practice. Rhenium complexes with 1,2-dihydroxybenzene, 4-methyl-1,2-dihydroxybenzene and 2,3- dihydroxynaphtalene were prepared and characterized by HRMS. Fragmentation mechanisms of the complexes were studied using information gathered from collision cell experiments.
