Yi, Xiao; Chen, Jing; Xu, Xiuling; Ma, Yongmin published an article in 2017, the title of the article was Solvent and substituent effects on the conversion of 4-methoxypyridines to N-methyl-4-pyridones.Formula: C6H5Br2NO And the article contains the following content:
In the reaction of 4-methoxypyridine derivatives with alkyl iodides in the presence or absence of solvent, not only the pyridinium ions but also the related 1-methylpyridones are produced. The presence of solvent favors the formation of the 1-methylpyridone. Electron withdrawing groups on the pyridine ring also favor this conversion. A possible mechanism is presented. The experimental process involved the reaction of 3,5-Dibromo-4-methoxypyridine(cas: 25813-24-5).Formula: C6H5Br2NO
The Article related to solvent substituent effect methoxypyridine derivative alkyl iodide pyridone, Physical Organic Chemistry: Addition, Elimination, and Substitution Reactions and other aspects.Formula: C6H5Br2NO
