Abstract

V sklopu magistrske naloge sem sintetiziral štiriindvajset različnih selenidov in selenoksidov. Najprej sem sintetiziral sedemnajst različnih simetričnih in nesimetričnih selenidov, nato pa sedem izbranih selenidov oksidiral do selenoksidov. V prvem sklopu sem iz aril bromidov in elementarnega selena preko modificirane Grignardove reakcije sintetiziral devet simetričnih selenidov. V drugem sklopu sem pri sobni temperaturi iz difenil diselenida in različnih aktiviranih aromatov pripravil osem nesimetričnih selenidov. Pri teh reakcijah sem kot reagent uporabil Selectfluor$^{TM}$ (F-TEDA) ali PIFA ((bis(trifluoroacetoksi)jodo)benzen). V zadnjem sklopu sem sedem izbranih selenidov oksidiral do selenoksidov z uporabo vodikovega peroksida brez uporabe topil.

Secondary title: Synthesis and some conversions of organoselenium compounds
Secondary abstract: For my master's thesis I have synthesised twenty-four different selenides and selenoxides. First, I synthesised seventeen different symmetrical and unsymmetrical selenides, then I have oxidised seven selected selenides to selenoxides. In the first part I have synthesised nine different symmetrical selenides using aryl bromides and elementary selenium in a modified Grignard reaction. In the second part I have used diphenyl diselenide and various activated aromatic compounds to synthesize eight different unsymmetric selenides at room temperature. In these reactions I have used Selectfluor$^{TM}$ (F-TEDA) or PIFA ((bis(trifluoroacetoxy)iodo)benzene) as a reagent. In the last part I have oxidised seven of the selenides into selenoxides using hydrogen peroxide without the use of solvents.
