Abstract

Cilj ovog rada je pripremiti nove simetrične derivate skvareinske kiseline kroz nekoliko koraka. Prvi korak uključuje aminaciju početnog spoja 1-brom-3,5-dimetoksibenzena odgovarajućim aminom, pri čemu su dobiveni produkti 1 i 2. U drugom koraku se spojevi 1 i 2 podvrgavaju demetiliranju do alkoholnih derivata 3- 5. U posljednjem koraku dolazi do kondenzacije sa skvareinskom kiselinom te nastaju produkti 6- 8. U sklopu rada sintetiziran je i dialilni metoksi-derivat skvareinske kiseline 9, kako bi se dodatno ispitao utjecaj supstituenata na svojstva skvareina. Nadalje, svi produkti i međuprodukti u potpunosti su spektroskopski okarakterizirani.

Abstract (english)

The aim of this work is to prepare new symmetric derivatives of squaric acid through several steps. The first step involves amination of the starting compound 1-bromo-3,5-dimethoxybenzene with the appropriate amine to give products 1 and 2. In the second step, compounds 1 and 2 are demethylated to alcohol derivatives 3- 5. In the last step, condensation with squaric acid occurs and products 6-8 are formed. As part of the work, a diallyl methoxy derivative of squaric acid 9 was synthesized in order to further investigate the influence of substituents on the properties of squarein. Furthermore, all products and intermediates were fully spectroscopically characterized.
