Nitration of relatively electron-rich arenes does not require an additive or a solvent. For example, reaction on a gram scale of anisole with acetyl nitrate, generated in situ by mixing 100% HNO3 with acetic anhydride, produced 2,4-dinitroanisole in 82% yield after crystallization of the crude product. Results with five additional monosubstituted benzene derivatives possessing highly activated, weakly activated, or weakly deactivated rings are reported.
