Solov’eva, I. A. published the artcilePreparation of secondary aromatic and aliphatic aromatic amines via the Smiles rearrangement, COA of Formula: C12H9N3O4, the publication is Zhurnal Organicheskoi Khimii (1968), 4(11), 1973-9, database is CAplus.
The easily accessible amides p-O2NC6H4-OCH2CONHR [where R is Me, Et, PhCH2, Ph, ¦Á-naphthyl, ¦Â-naphthyl, p-PhC6H4, o-PhC6H4, p-ClC6H4, p-O2NC6H4, o-Et2NC6H4, p-HO2CC6H4, o-MeOC6H4, o-HO2CC6H4, 2,5-HO2C(O2N)C6H4, or 4,2-Cl(HO2C)C6H4] undergo Smiles rearrangement and give amines p-O2NC6H4NHR (R as above). Under the same reaction conditions m-O2NC6H4OCH2CONHR or PhOCH2CONHR (where R is Me, Et, PhCH2, or Ph) decompose to m-O2NC6H4OCH2CO2H and NH2R. o-O2NC6H4-OCH2CONH2 or p-O2NC6H4OCH2CONH2 give only very low yields of the corresponding nitroanilines; the disubstituted amides o-O2NC6H4OCH2CONRR1 or p-O2NC6H4OCH2-CONNR1 do not rearrange.
Zhurnal Organicheskoi Khimii published new progress about 1821-27-8. 1821-27-8 belongs to catalysis-chemistry, auxiliary class Nitro Compound,Amine,Benzene, name is Bis(4-nitrophenyl)amine, and the molecular formula is C6H8O6, COA of Formula: C12H9N3O4.
