《Reexamination of the application of linear free energy relationships to the azaheterocyclic systems. I. Substituent effects on the basicity of monocyclic azines》 was written by Tomasik, P.; Zalewski, R.. Electric Literature of C6H8N2O And the article was included in Chemicke Zvesti on April 30 ,1977. The article conveys some information:
The basicities of pyridines, pyrimidines, pyridazines, and pyrazines (180 compounds) were correlated with substituent effects by Hammett and Taft equations. Limitations of the LFER are discussed. In addition to this study using 2-Methoxy-4-methylpyrimidine, there are many other studies that have used 2-Methoxy-4-methylpyrimidine(cas: 14001-60-6Electric Literature of C6H8N2O) was used in this study.
2-Methoxy-4-methylpyrimidine(cas: 14001-60-6) is a member of ether. When aromatic ethers are exposed to halogen in the presence or absence of a catalyst, they undergo halogenation, such as bromination.Electric Literature of C6H8N2O
