Deady, Leslie W.; Korytsky, Olga L.; Rowe, Jeffrey E. published the artcile< Substituent effects on the isomer ratios in the rearrangement of some 2- and 4-nitraminopyridines>, SDS of cas: 21901-29-1, the main research area is substituent effect rearrangement nitraminopyridine.
The preparation and rearrangement in 92% H2SO4 of I-III (R = H, Me, MeO, Br, Cl, CO2H) were investigated. The product isomer ratios can be explained by differential electronic stabilization of the appropriate σ complexes for aromatic nitration and steric effects seem relatively unimportant. Deuteration [3-D in I, R = Me] had no effect on the product distribution.
Australian Journal of Chemistry published new progress about Rearrangement. 21901-29-1 belongs to class pyridine-derivatives, and the molecular formula is C6H7N3O2, SDS of cas: 21901-29-1.
