Redoks reakcije, ki potečejo po absorpciji fotonov, omogočajo pripravo in funkcionalizacijo
heterocikličnih spojin pod blagimi reakcijskimi pogoji. Od teh smo se osredotočili na pretvorbe
spojin s pirazolnim skeletom.
Pod vidno svetlobo v prisotnosti fotoredoks katalizatorja eozina ter kisi ...

By utilizing an underexplored reactivity of N1-substituted pyrazolidine-3-ones, we developed a visible-light-induced aerobic oxidation of N1-substituted pyrazolidine-3-one derivatives yielding the corresponding azomethine imines. The resulting azomethine imines can be further reacted with ynones in ...

Sulfonyl chlorides are a synthetically attractive source of sulfonyl radicals in photoredox catalysis and are useful precursors in the synthesis of sulfones. Sulfamoyl chlorides, on the other hand, remain poorly represented despite their similar potential. In this study, N-chlorosulfonylated β-lacta ...

Irradiation of mixtures of title diazonium salts and heteroarenes with green light (510 nm) in the presence of eosin Y disodium salt (EY-Na$_2$) as a photocatalyst furnished the corresponding arylation products in 8−63% yields. The proposed photocatalytic cycle is analogous to that proposed previous ...

A series of thirteen 2-acyl-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazole derivatives were synthesized by using a copper-catalyzed azomethine-imine-alkyne cycloaddition as a key step. These bimane-related fluorescent compounds with λ$_{ex}$ = 338–400 nm and λ$_{em}$ = 522–644 nm exhibit interesting and ...

Parkinson’s disease (PD) has emerged as the second most common form of human neurodegenerative disorders. However, due to the severe side effects of the current antiparkinsonian drugs, the design of novel and safe compounds is a hot topic amongst the medicinal chemistry community. Herein, a convenie ...

Za Slovenijo so značilni padavinski dogodki visoke intenzitete in krajšega trajanja, kar jo uvršča med območja z višjimi vrednostmi erozivnosti padavin v Evropi. V magistrski nalogi je predstavljeno stanje na področju analiz erozivnosti padavin in z njo povzročene erozije tal; opisane so vrste erozi ...
