(E)-1-(2,4-Dinitro-phen-yl)-2-(2-fluoro-benzyl-idene)hydrazine
Abstract:
In the title compound, C(13)H(9)FN(4)O(4), the dihedral angle between the mean planes of the two benzene rings of the nearly planar mol-ecule is 6.6 (9)°. The dihedral angles between the mean planes of the benzene ring and its two attached nitro groups are 6.7 (7) and 7.2 (9)°. Crystal packing is stabilized by N-H⋯O hydrogen bonds, weak C-H⋯O and C-H⋯F inter-molecular inter-actions and centroid-centroid π-ring stacking inter-actions.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
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...
