摘要：

The synthesis of new hybrides 1,3,4-oxadiazol-2-thione with acridine 9(10H)-one is carried out. Their structure is confirmed by LC-MS, IR-, H-1 and C-13 NMR-spectroscopy. The thione-thiol equilibrium was investigated in eight solvents with different relative permittivity with the help of UV-spectroscopy and quantum chemistry methods using DFT/B3LYP and HF bases. The results of the experimental calculations are in agreement with theoretical ones and have shown the prevalence of the thione. There were established centers for reactions with the mechanism S-E and A(E), taking into account the electronic structural formulas and the results of calculating the atom charges of compounds.
