Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 59782-89-7, is researched, SMILESS is CC1=CC(I)=CN=C1Cl, Molecular C6H5ClINJournal, Journal of Chemical and Engineering Data called Some 2,5- and 5,6-dihalonicotinic acids and their precursors. IV, Author is Setliff, Frank L.; Lane, Julie E., the main research direction is pyridinecarboxylic acid dihalo; nicotinic acid dihalo; oxidation picoline; chloropyridinecarboxylic acid.Name: 2-Chloro-5-iodo-3-methylpyridine.
The pyridinecarboxylic acids I (R = Cl, R1 = CO2H, R2 = Cl, iodo; R = Cl, R1 = Cl, iodo, R2 = CO2H) were prepared by oxidation of I (R = Cl, R1 = Me, R2 = Cl, iodo; R = Cl, R1 = Cl, iodo, R2 = Me; resp.), which were prepared by diazotization and substitution of I (R = Cl, R1 = Me, R2 = NH2; R = Cl, R1 = NH2, R2 = Me; resp.). I (R = R1 = Cl, R2 = CO2H) and NaI gave I (R = iodo, R1 = Cl, R2 = CO2H).
I hope my short article helps more people learn about this compound(2-Chloro-5-iodo-3-methylpyridine)Name: 2-Chloro-5-iodo-3-methylpyridine. Apart from the compound(59782-89-7), you can read my other articles to know other related compounds.
