Compounds, N,N0-bis-(3,5-dichloroph

Compounds, N,N0-bis-(3,5-dichlorophenyl) isophthalamide (1)N,N0-bis-(3,5-difluorophenyl)isophthalamide (2) and N,N0-bis-(3,5-bis-(trifluoromethyl) phenyl)isophthalamide (3) N,N0-bis-(3,5-dichlorophenyl)pyridine-2,6dicarboxamide (4) N,N0-bis-(3,5-difluorophenyl) pyridine-2,6dicarboxamide (5) and N,N0-bis-(3,5-bis
(trifluoromethyl)phenyl)pyridine-2,6dicarboxamide (6) were synthesized by the coupling reactions of isophthaloyl chloride, pyridine-2,6-dicarbonyl chloride and 3,5-dichloroaniline, 3,5-difluoroaniline and 3,5 bis(trifluoromethyl) aniline correspondingly. For receptors 2,6-bis(3,5-dichlorophenyl carbamoyl)pyridinium (7) 2,6-bis(3,5-difluorophenyl carbamoyl)pyridinium (8) and 2,6-bis(3,5-bis (trifluoromethyl) phenylcarbamoyl)pyridinium (9) were prepared by the addition of protons to the compounds 4, 5 and 6 with hexafluorophosphoric acid. The compounds 1–9 and their complexes with TBACl, TBABr, TBAH2PO4, TBAHSO4 and TBANO3were studied
by proton NMR titration and DFT methods. The optimized structures of relevant receptors and their complexes with F, Cl, Br, H2PO4 ,HSO4 and NO
3 were obtained using the DFT/B3LYP/6-31+G(d)method. Thermodynamic properties of their associations derived fromfrequency DFT/B3LYP/6-31+G(d) computations are reported. The B3LYP/6-31+G(d) optimized structures for compounds 1, 2, 3 and 6
as syn–anti, 4 and 5 as syn–syn, and 7, 8 and 9 as anti–anti conformations
were found. The most favorable complex of compound 3 with
Br was found by NMR method. High association constants of compounds
1–6 with F are expected and the highest association constant
of compound 6 with F is expected. Associations of all
receptors with anions are exothermic and spontaneous reactions.
