Synthesis of sulfur derivatives of pyridine and its N-oxide was written by Puszko, Aniela;Talik, Zofia. And the article was included in Polish Journal of Chemistry in 1991.Application In Synthesis of 2,4-Dibromo-5-methylpyridine This article mentions the following:
2,4-Pyridinedithiol N-oxide and three isomeric 2,4-picoline (3-Me, 5-Me, 6-Me) dithiol N-oxides were obtained by reaction of 2,4-dichloropyridine N-oxide and 2,4-dihalogenopicoline N-oxides with thioacetamide. 2,4-Pyridinedithiol N-oxide and 3-methylpyridine-2,4-dithiol N-oxide were deoxidized by treatment with PBr3. In the experiment, the researchers used many compounds, for example, 2,4-Dibromo-5-methylpyridine (cas: 79055-50-8Application In Synthesis of 2,4-Dibromo-5-methylpyridine).
2,4-Dibromo-5-methylpyridine (cas: 79055-50-8) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Application In Synthesis of 2,4-Dibromo-5-methylpyridine
