diplomsko delo

Abstract

V okviru diplomskega dela sem pripravila izhodni kompleks paladija s PCP kleščo tBu(PCP)Pd−Cl. V nadaljevanju sem izvedla pretvorbo tega kompleksa v ustrezen nitro, hidroksi in acetoksi derivat: tBu(PCP)Pd−ONO2, tBu(PCP)Pd−OH ter tBu(PCP)Pd−acac. Izvedla sem tudi testno Michaelovo adicijo metil acetoacetata na nitrostiren z uporabo tBu(PCP)Pd−acac kompleksa kot katalizatorja. Reakcije sem zasledovala z uporabo tankoplastne kromatografije, njihovo uspešnost pa sem preverjala z 1H in 31P NMR ter IR spektroskopijo.

Secondary title: Preparation of pincer complexes with palladium and study of their reactivity
Secondary abstract: As part of my thesis work I prepared the starting palladium complex using PCP pincer as the ligand tBu(PCP)Pd-Cl. Subsequently, this complex was converted into the corresponding nitro, hydroxy and acetoxy derivatives: tBu(PCP)Pd−ONO2, tBu(PCP)Pd− OH and tBu(PCP)Pd−acac. I also performed a test involving the Michael addition of methyl acetoacetate to nitrostyrene using the tBu(PCP)Pd−acac complex as the catalyst. The reactions were monitored by thin layer chromatography and their success was verified by 1H and 31P NMR and IR spectroscopy.
