An amide-assisted arene nitration is presented, and both mono- and dinitration of protected anilines could be effected by using NaNO2 and NaNO3 as the mono- and bisnitrating agents, respectively. This divergent synthesis is transition-metal- and acid-free, and features a broad substrate scope, low cost, and ortho–para selectivity.

Aromatic amides bearing 2-azulenyl group on the amide nitrogen were synthesized and their structures were investigated. The π-electron density of the N-aryl group was found to influence the cis-trans conformational preferences of these compounds in solution. X-ray crystallography revealed that the plane of the 2-azulenyl ring has a strong tendency to lie coplanar with the amide plane when the azulene group is located on the same side as the amide oxygen atom.

Acetic acid has been used for acetylation of seven aromatic amines and two phenols under microwave exposure. The time taken for these reactions ranges from 18-25 min with reasonability good yields (65-77%).
