(E)-1-(2,4-Dinitro-phen-yl)-2-[1-(4-fluoro-phen-yl)ethyl-idene]hydrazine
Abstract:
The title compound, C(14)H(11)FN(4)O(4), crystallizes with two essentially planar mol-ecules in the asymmetric unit; the dihedral angles between the benzene rings are 1.57 (15) and 6.17 (15)°. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯F inter-actions into sheets lying parallel to (120). O⋯C [2.980 (4) Å] and O⋯N [2.892 (3) Å] short contacts also occur.

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...
