Abstract
U okviru ovoga završnog rada opisan je pokušaj priprave naftalimidnog derivata, spoja (2) s ciljem njegove primjene u detekciji sumporovodika (H2S). Za pripravu ciljnog spoja (2) predložen je sintetski put koji se sastoji od dva sintetska koraka. Kao polazni spoj korišten je 4-brom-1,8-naftalanhidrid. Prvi reakcijski korak podrazumijevao je uvođenje azidne skupine u osnovnu naftalanhidridnu strukturu, odnosno pripravu spoja 1, kao receptora odgovornog za prepoznavanje analita (H2S). Spoj 1 uspješno je pripravljen reakcijom 4-brom-1,8-naftalanhidrida i natrijeva azida (NaN3) u suhom dimetilformamidu (DMF). Struktura spoja pretpostavljena je FTIR spektroskopijom. S ciljem priprave odgovarajućeg naftalimidnog derivata, spoja 2, spoj 1 podvrgnut je adicijskog-eliminacijskoj reakciji s dodecilaminom u etanolu kao otapalu zagrijavanjem uz povratno hladilo. Dobivenu smjesu produkata pokušalo se razdvojiti kromatografijom na stupcu uz sustav otapala etil-acetat/heksan, 1:1. Kromatografijom na stupcu razdvojene su dvije glavne frakcije koje fluoresciraju pod UV lampom (365 nm) žutom i plavom bojom. Na temelju IR spektroskopije zaključeno je kako niti jedna od razdvojenih frakcija ne odgovara planiranoj strukturi spoja 2.
Abstract (english)
In this thesis, we describe an experiment to prepare a naphthalimide derivative, a compound of formula (2), to detect hydrogen sulfide (H2S). A synthetic route consisting of two synthetic steps has been proposed for the preparation of the target compound (2). 4-bromo-1,8-naphthalene anhydride was used as the starting compound. The first reaction step was the introduction of an azide group into the basic structure of the naphthalene hydride, i.e. the preparation of compound (1) as the receptor responsible for the recognition of the analyte (H2S). Compound (1) was successfully prepared by reacting 4-bromo-1,8-naphthalene anhydride with sodium azide (NaN3) in dry dimethylformamide (DMF). The structure of compound (I) was suggested by FTIR spectroscopy. In order to prepare the corresponding naphthalimide derivative, compound (2), compound (1) was subjected to an addition-elimination reaction in ethanol in solvent under refluxing refrigeration. The resulting product mixture was separated using a 1:1 ethyl acetate/hexane solvent mixture by column chromatography. Column chromatography was used to separate the two main fractions, which showed yellow and blue fluorescence under UV light (365 nm). Based on IR spectroscopy, it was concluded that neither of the separated fractions corresponded to the designed structure of compound 2.
