Abstract:
The title compound, C(14)H(11)N(3)O(3), adopts an E or trans configuration with respect to the C=N bond. In the mol-ecule there is an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy substituent at the 2-positon of the naphthalene ring and the adjacent methyl-ene-amino N atom. The mol-ecule is roughly planar, the dihedral angle between the naphthalene and imidazolidine-2,4-dione mean planes being 8.4 (1)°. In the crystal, pairs of N-H⋯O hydrogen bonds link mol-ecules into inversion dimers. These dimers are futher linked via C-H⋯O inter-actions, forming a three-dimensional network.

Diazonium Group Substitution: –OH and –H
Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...

Imines are formed under mildly acidic conditions. A pH of 4.5 is ideal for the reaction.
If the pH is low or the solution is too acidic, the reaction slows down in the...
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...
