Abstract
1. Some 2-aryl-3-hydroxypyridine N-oxides were synthesized. 2. A study was made of the effect of the N-oxide group on the orientation in electrophilic reactions that proceed both in theβ-pyridinol ring and in the phenyl ring of the molecule. The N-oxide group affects the reactivity of theβ-pyridinol ring and the orientation of the substitution only in the iodination reaction.
