Abstract
V zadnjem času se krepi zavedanje, da mora boj za ohranitev človeku prijaznega okolja potekati na vseh ravneh. Temu primerno se stopnjuje tudi zanimanje in novi načini reakcij pod zelenimi pogoji. Aromatski ketoni so sestavine mnogih različnih snovi. Prisotni so v farmacevtskih izdelkih, naravnih proizvodih in sredstvih za zaščito pridelkov. V diplomi je predstavljeno Friedel-Craftsovo aciliranje polisubstituiranih in aktiviranih aromatskih spojin z enim ali dvema obročema. Substituenti so metoksi in metilne skupine. Reakcije so bile z eno izjemo izvedene brez kovinskega katalizatorja in z bistveno manj proizvedenega odpadka kot pri klasični sintezi. Ena reakcija je bila zaradi neuspeha pod zelenimi pogoji izvedena na klasičen način z etanoil kloridom in AlCl3. Nekateri nastali produkti v trenutno razpoložljivi literaturi še niso opisani.

Title:Some environmentally-friendly transformations
Abstract:
Recently, there has been a growing awareness that the fight to preserve a human-friendly environment must take place at all levels. Correspondingly, interest and new ways of reacting under green conditions are also increasing. Aromatic ketones are components of many different substances. They are present in pharmaceutical products, natural products and agrochemicals. The thesis presents Friedel-Crafts acylation of polysubstituted and activated aromatic compounds with one or two rings. Substituents are methoxy and methyl groups. With one exception, the reactions were carried out without a metal catalyst and with significantly less produced waste than in classic synthesis. One reaction was performed under traditional conditions with acetyl chloride and AlCl3 due to the failure of the reaction under green conditions. Some of the resulting products have not yet been described in the currently available literature.

Keywords:Friedel-Crafts acylation, green chemistry, substitution, polysubstituted arenes, activated arenes
