N-oxides and related compounds. Part XLVI. Chemical and physical properties of pyridine 1-nitroimides and comparison with quantum chemical predictions
Abstract
Molecular orbital treatment of pyridine 1-nitroimide predicts well the site of protonation, u.v. spectrum, and reactivity. The ring resists electrophillic attack but α-protons are readily replaced by deuterium in the presence of base. The mass spectral framentation is elucidated.
