Odashima, Tsugikatsu published the artcileSynthesis and properties of 3-, 4-, and 5-nitro-2-pyridinecarboxaldehyde 2-pyridylhydrazones and characterization of their metal complexes, Synthetic Route of 2215-33-0, the publication is Bulletin of the Chemical Society of Japan (1993), 66(3), 797-803, database is CAplus.
Three title hydrazones (I, R = 3-, 4-, and 5-NO2), were synthesized. Their properties and reactivities with metal ions and the extraction and characteristics of the resultant complexes were investigated and compared with one another. As a result, useful information on the mol. design of highly sensitive hydrazone reagents was obtained.
Bulletin of the Chemical Society of Japan published new progress about 2215-33-0. 2215-33-0 belongs to pyridine-derivatives, auxiliary class Pyridine,Amine, name is 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, and the molecular formula is C11H10N4, Synthetic Route of 2215-33-0.
