Abstract

New dissymmetric and asymmetric p-tert-butylthiacalix[4]arene derivatives were prepared as a result of the reaction of p-tert-butylthiacalix[4]arene with diethyl bromomalonate in the presence of different alkali metals (Cs, K and Na) in refluxing acetone for 7 days. The structures of the prepared compounds were investigated by IR, 1H-NMR and MALDI-TOF mass spectroscopy.
Keywords: Thiacalix[4]arene; asymmetry; diethyl bromomalonate Thiacalix[4]arene; asymmetry; diethyl bromomalonate
