Aromatic Nitro group Displacement Reactions. Part 2. The Synthesis of Diarylamines and some Heteroaromatic Analogues.

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.
