An improved procedure for the preparation of aromatic heterocyclic N-oxides was written by Rhie, Soo Young;Ryu, Eung K.. And the article was included in Heterocycles in 1995.Safety of 3,5-Dimethylpyridine 1-oxide This article mentions the following:
Nitrogen-containing heterocyclic compounds gave their N-oxides in excellent yields by reaction with m-chloroperbenzoic acid in DMF/MeOH in the presence of HF. The presence of HF and MeOH is crucial for the reaction. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Safety of 3,5-Dimethylpyridine 1-oxide).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Safety of 3,5-Dimethylpyridine 1-oxide
