Ag. Giumanini et al., N-NITROSO AND C-NITRO DERIVATIVES FROM DI-(2-PYRIDYL)AMINE AND BUTYL NITRITE, Bulletin of the Chemical Society of Japan, 67(6), 1994, pp. 1641-1645
The reaction between di-(2-pyridyl)amine and butyl nitrite produced N-
introsodi-(2-pyridyl)amine, (5-nitro-2-pyridyl)-2-pyridylamine and (3-
nitro-2-pyridyl)-2-pyridylamine of which the likely conformations are
evinced from spectral data. Structural elucidation of N-nitrosodi-(2-p
yridyl)amine in the solid state by X-ray diffraction excluded any subs
tantial contribution of the rings to resonance structures.
