“…Upravo to je glavni razlog zašto se ta vrsta spojeva danas istražuje ponajprije u svrhu uklanjanja viška navedenih metala iz organizma odnosno kao potencijalni kelatoterapeutici. Zbog svojih kelirajućih svojstava, osim u farmaceutske svrhe, ti se spojevi dodatno istražuju i u analitičkoj kemiji za ekstrakciju 6,8,17,[23][24][25] pojedinih metala iz vodenih otopina, pri čemu se sastav nastalih kompleksa i sposobnost keliranja liganda najčešće određu-ju UV-Vis-spektrofotometrijskim tehnikama.…”

“…In continuation of our work on the synthesis and properties of 3,4-HPO derivatives 11,19,20 and research in the field of coordinating capabilities of vanadium complexes 21 we report a single step synthesis of 3-hydroxy-1-(p-methoxyphenyl)-2-methylpyridine-4-one (HM) which we optimized by using the adequate catalyst and appropriate reaction time to obtain the most satisfactory yield. Detailed spectrophotometric studies of the extraction of vanadium(V) with HM from water solutions into chloroform are also described.…”

Abstract. In this paper a single step synthesis of 3-hydroxy-1-(p-methoxyphenyl)-2-methylpyridine-4-one (HM) using starting maltol and p-anisidine in the presence of acid catalyst (p-toluenesulfonic acid or HCl) is described. The reaction is carried out by heating the aqueous solution of the reactants and a catalyst in a sealed thick-walled glass tube at 150 °C at different reaction times in order to retrieve an optimal yield. The complexation reactions of vanadium(V) with HM as well as the extraction of V(V) from aqueous to organic phase were studied spectrophotometrically. The optimum conditions for extraction of vanadium(V) from aqueous phase, containing chloride or thiocyanate ions, to chloroform solution of HM and complex formation have been evaluated. Based on the results obtained by Job's and equilibrium shift methods the composition of the complexes has been found to be V(V) : Cl(SCN) : HM = 1:1:2.
