Presented diploma thesis follows the long-term study running at the Department of Organic Chemistry at the University of Chemistry and Technology Prague in the field of using flavinium salts as catalysts of oxidation reactions. The aim was to verify the reactivity of flavinium salt 13 with different types of O- and N-nucleophiles by monitoring of the corresponding C4a-adducts formation. In the thesis a simple alloxazinium salt 13 and one of the nucleophiles (hydroxylamine 25) were prepared. According to the results obtained from the UV-VIS measurements nucleophile 25 is the only one of the newly tested wchich formed desired C4a-adduct 13d with alloxazinium salt 13.
