Full TextAbstract
The synthesis of some novel crown and thiacrown ethers via the reaction of 2,3-bis(4- hydroxyphenyl) or 2,3-bis(4-mercaptophenyl)quinoxalines and pyridopyridazine with diethylene and triethylene glycol ditosylate is described. The complexing ability of compounds 5b and 5h, as the representatives of both groups of compounds, with alkali and alkali earth metal cations were measured by the solvent extraction method. The results showed that crown ether 5b comparatively had more affinity towards the Mg2+ cation, while thiacrown ether 5h had greater affinity towards the Ca2+ cation.
