Abstract:
In the title compound, C(26)H(24)Br(2)N(2)O(2), the central naphthalene system carries two Br atoms and two -CH(2)CH(2)NHC(6)H(5) substituents. The phenyl rings of the latter residues are inclined at 74.17 (17) and 51.4 (2)° with respect to the naphthalene ring system. Each alkyl chain adopts a fully extended all-cis conformation with respect to the naphthalene and phenyl rings [N-C-C-O torsion angles = 68.6 (4) and 60.5 (4)°]. In the crystal, one of the N-H groups forms bifurcated N-H⋯(Br,O) hydrogen bonds, which link the mol-ecules into inversion-related dimers. The centrosymmetric dimers are aggregated via pairs of C-H⋯π inter-actions into sheets parallel to (110).

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
