Sinteza selenidov in njihove oksidacijske pretvorbe

Likovič, Tine (author), Jereb, Marjan (mentor)

V magistrski nalogi sem sintetiziral različne selenide in jih naprej oksidiral do selenoksidov. Selenide kot izhodne spojine selenoksidov sem sintetiziral po že znanih metodah. Nato sem s temi spojinami izvajal reakcije pod oksidativnimi pogoji z uporabo zelenega oksidanta 30 % vodne raztopine H2O2. Uspešno sem izoliral in očistil dobljene produkte – selenokside. Izkoristki reakcij so med 26 % in 97 %. Vse nove produkte sem okarakteriziral z 1H, 19F in 13C NMR, IR spektroskopijo in HRMS (masno spektrometrijo visoke ločljivosti). Trdnim produktom sem izmeril še temperaturo tališča.

Abstract

In my master thesis I synthesised different selenides and submitted them to oxidative conditions. I synthesised selenides as selenoxides' parent compounds by already known methods. Then, I carried out the reactions with these synthesised selenides under oxidative conditions using the green water-based oxidant, 30 % aqueous solution of H2O2. I have successfully isolated and purified the resulting products - selenoxides. Isolated yields are between 26 % and 97 %. All new products were characterised by 1H, 19F and 13C NMR, IR spectroscopy and HRMS (high resolution mass spectrometry). For solid products, I also measured the melting point.
