, p. 349 - 354 (2007/10/02)

A series of 3H-pyridobenzotriazin-4-ylium-3-ides has been synthesised by reaction of 8-acylaminoquinolines with O-mesitylenesulphonylhydroxylamine followed by treatment with aqueous alkali.The spectral (u.v., 1H n.m.r., and 13C n.m.r. spectra) and chemical properties (bromination and 1,3-dipolar cycloaddition) of the new mesomeric betains have been investigated.
