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.
The Synthesis of Diarylamines by Nitro-group Displacement. Activation of Anilines containing Electron-withdrawing Groups by Potassium Carbonate
Gorvin, John H.
, p. 238 - 239 (2007/10/02)
Anilines of enhanced N-acidity can displace activated aromatic nitro-groups in dipolar aprotic solvents in the presence of potassium carbonate; the resulting diarylamines are generally obtained free of triarylamine and of the hydrogen displacement product.
