We report a catalyst-free ipso-nitration of aryl boronic acids using bismuth (III) nitrate as nitrating agent. Reaction proceeds in shorter reaction times with moderate to excellent yields. This method is operationally simple, regioselective, and possesses excellent functional group compatibility to synthesize nitroarenes.
An efficient and one pot synthetic method of ipso-nitration of arylboronic acids has been developed. The high efficiency, general applicability, and broader substrate scope including heterocycles and functional groups make this method advantageous. Due to its simplicity, we expect to find application of this method in synthesis.

A novel, simple and efficient ipso-nitration of arylboronic acids with iron nitrate has been developed. The protocol uses readily available arylboronic acids as the starting materials, inexpensive iron nitrate (0.5 equiv.) as the nitro source without addition of an additive, and the corresponding nitroarenes were obtained in good to excellent yields.
