Реферат:
We report studies on the Pd(II) and Ag(I) complexation and extraction by tetraalkyl(tolyl)thiomethylcalix[4]arenes (1a–c) stabilized in the cone conformation, and by the stereochemically mobile tetraalkyl(tolyl)thiomethylcalix[6]arenes (2a, b). These are found to be 100–1000 times more efficient as extractants of nitric and nitrous forms of Pd(II) and Ag(I) than their ungrafted monodentate analogues. Extraction experiments performed on real HLW show that tetrabutylthiomethylcalix[4]arene 1b is able to concentrate and separate Pd from main fission products. The extraction constants for mono‐ and binuclear Ag complexes have been determined. The stoichiometry and structural features of the complexes of Pd and Ag have been studied experimentally by extraction, IR‐ and mass‐spectroscopy methods as well as in quantum‐mechanical calculations.
