With the help of Nuclear Overhauser Effect spectroscopy it became possible to specify the structure of 6-hydrazino(alkylhydrazino)-4-methyl-2-chloronicotinonitriles I (R = H, Me, Et). In the experiment, the researchers used many compounds, for example, 2-Chloro-4-methylpyridine-3-carbonitrile (cas: 65169-38-2COA of Formula: C7H5ClN2).
2-Chloro-4-methylpyridine-3-carbonitrile (cas: 65169-38-2) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.COA of Formula: C7H5ClN2
