Nitration of Quinoline-N-oxide having Substituent in its Benzene Ring

Abstract

In the nitration of quinoline-N-oxides having halogen in its benzene ring, such as 6-chloro-, 6-bromo- and 8-chloro compounds, effect of N-oxide radical on its C₄ position is decreased by halogen radical and nitration occurs at C₅ position.
