Abstract

A new polyether macrocyclic of 1-pyrazolylbenzimidazol-2-ones 5-6 have been synthesized by the reaction of dichloro(poly)ethylene glycol in phase transfer catalysis conditions.

The structure of these compounds were identified by 1H NMR, 13C NMR, IR spectroscopy and Mass spectrometry. The formation of Li+, Na+, and K+ complexes with compounds 5-6 has been investigated by UV-visible spectroscopy. It was demonstrated that ligand 5 form preferentialcomplex with Li+ cation.
