Abstract:
A new dinitrogen (N2) molybdenum(0) complex supported exclusively by pyridine ligands was synthesized. The X-ray crystal structure of the complex elucidated the activated nature of the N2 ligand, consistent with a low N-N IR stretching frequency. Natural bond orbital (NBO) analyses on this system confirmed a strong π-backdonation arising from the large p orbital character in molybdenum lone pairs. The protonation of the N2 ligand using decamethyl chromocene (CrCp*2) in the presence of lutidinium salt afforded 1.22 equivalents of ammonia (NH3).

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...
