Abstract:
Derivatives based on pyridine-2-6- and furan-2,5-dicarboxamide scaffolds reveal numerous chemical properties and biological activities. This fact makes them an exciting research topic in supramolecular and coordination chemistry and in discovering new pharmacologically-active compounds. This work aimed to obtain a series of symmetrical pyridine-2-6- and furan-2,5-dicarboxamides through a condensation reaction of the appropriate acyl chlorides and aromatic amides. Successful syntheses were confirmed with NMR spectroscopy. We solved their crystal structures for seven compounds; two pyridine and

Abstract:
The proton affinity ( PA) of cyclopentane carboxamide 1, cyclohexane carboxamide 2 and their secondary and tertiary amide derivatives S1, S2, T1 and T2, was determined by the thermokinetic method and the kinetic method [ PA(1) = 888 ± 5 kJ mol−1; PA(2) = 892 ± 5 kJ mol−1; PA(S1) = 920 ± 6 kJ mol−1; PA(S2) = 920 ± 6 kJ mol−1; PA(T1) = 938 ± 6 kJ mol−1; PA(T2) = 938 ± 6 kJ mol−1]. Special entropy effects are not observed. Additionally, the effects of protonation have been studied using an advanced kinetic method for all isomers 3–7 of cyclopentane dicarboxamides and cyclohexane dicarboxamides (w

A green chemistry method was applied in the synthesis of N2,N6-bis(6-iodo-2-methyl-4-oxoquinazolin-3(4H)-yl)pyridine-2,6-dicarboxamide. The desired compound was synthesized mechanochemically, using a choline chloride-based deep eutectic solvent as a catalyst. The synthesis took 20 min and the new compound was characterized using different spectral methods.

We have carried out a theoretic research of plasticity for the coordination and noncovalent bonds modelling uniaxial mechanical deformation of the crystal cell of bis(2-N,6-N-dibutylpyridin-2,6-dicarboxamide)-nickel (II) dichloride. For this purpose, we have modeled stretching deformation of the crystal structure along its crystallographic axes using the 3-corrected Hartree-Fock method with the following semi-empirical corrections for the weak interactions (the Grimme correction of dispersion interactions, D3, basis set superposition error removal by the atom-pair wise geomet-rical counterpois

Abstract:
In the title compound, C8H7N3O4(systematic name: 4-nitrobenzene-1,2-dicarboxamide), each of the substituents is twisted out of the plane of the benzene ring to which it is attached [dihedral angles of 11.36 (2)° for the nitro group, and 60.89 (6) and 34.39 (6)° for the amide groups]. The amide groups are orientated to either side of the least-squares plane through the benzene ring with the amine groups being directed furthest apart. In the crystal, a three-dimensional architecture is established by a network of N—H...O hydrogen bonds.
