Abstract
The paper presents synthesis and characterization of azobenzene compound that contains 10 carbon atoms as flexible terminal chain and one fluorine atom as lateral polar substituent. The synthesis was achieved by diazotization of 4-amino benzoic acid and coupling of diazonium salt to 2-fluorophenole, followed by alkylation with a bromoalkyl compound. The synthetized compounds were purified and their structures were confirmed by 1H-NMR and 13C-NMR studies.
Keywords: diazotization, coupling, fluorine, alkylation.
