Abstract

V svojem diplomskem delu sem testirala pretvorbo elektronsko bogatih aromatov s karboksilnimi anhidridi in trifluoroocetno kislino (TFA). Reakcija je trajnostna alternativa klasični reakciji Friedel-Craftsovega aciliranja, saj omogoča sintezo brez uporabe toksičnega in nevarnega katalizatorja AlCl$_3$. TFA deluje kot katalizator in topilo hkrati, prav tako pa jo lahko po reakciji ponovno uporabimo in se tako izognemo nepotrebnemu odpadku. Aciliranje sem izvajala na spojinah z različno sterično zahtevnimi funkcionalnimi skupinami. Raziskovala sem tudi vpliv strukture elektronsko revnejših oziroma elektronsko bogatejših aromatov na potek aciliranja aromatskega obroča.

Secondary title: Conversions of electron-rich aromatic compounds under alternative conditions
Secondary abstract: In my thesis, I tested the conversion of electron-rich aromatic compounds with carboxylic anhydrides and trifluoroacetic acid (TFA). The reaction is a sustainable alternative to the classical Friedel-Crafts acylation reaction because it allows for synthesis without the use of the toxic and hazardous catalyst AlCl$_3$. TFA acts as both a catalyst and a solvent, and it can be reused after the reaction, thus avoiding unnecessary waste. I conducted acylation on compounds with functional groups with different steric requirements. I also investigated the influence of structure of electron-poor and electron-rich aromatic compounds on the acylation pathway.
