Aromatic Nitro-group Displacement Reactions. Part 3. Minor Products of the o-Cyanophenol Synthesis
Gorvin, John H.

In dipolar aprotic solvents, the action of cyanide ions on a moderately activated aromatic or heteroaromatic nitro-compound yields, in addition to the o-cyanophenol, a range of products generated through nitro-group reduction.
Aromatic Nitro group Displacement Reactions. Part 2. The Synthesis of Diarylamines and some Heteroaromatic Analogues.
Gorvin, John H.
, p. 1662 - 1681 (2007/10/02)
In dipolar aprotic solvents, activated aromatic nitro-groups can usually be displaced by anilines of enhanced N-acidity in the presence of the heavier alkali-metal carbonates.When catalysed by potassium t-butoxide, however, attack occurs preferentially at other reactive centers in the molecule, except where the nitro-group is highly activated.Some of the resulting diarylamines (the term is here expanded to include arylaminoxanthen-9-ones) are intermediates in the synthesis of heterocycles.
