Syntheses of Pyridazine Derivatives. VII. Reactivity of 3-Hydroxypyridazine 1-Oxide. (1).

Abstract

The reactivities of 3-hydroxypyridazine 1-oxide (I) were examined in bromination and acid-and base-catalyzed deuteration reactions. The electronic effects of 3-hydroxy and N-oxide groups were discussed in comparison of the reactivities of I with 3-hydroxypyridazine and pyridazine 1-oxide.
