1,3-Bis[4-(dimethyl-amino)benz-yl]-4,5,6,7-tetra-hydro-1H-1,3-diazepan-2-ium chloride
Abstract:
The title N-heterocyclic carbene derivative, C(23)H(33)N(4) (+)·Cl(-), has been synthesized and characterized by elemental analysis, (1)H and (13)C NMR, IR spectroscopy and a single-crystal X-ray diffraction study. Ions of the title compound are linked by three C-H⋯Cl inter-actions. The seven-membered 1,3-diazepane ring has a form inter-mediate between twist-chair and twist-boat.

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...
