We report a visible light-assisted one-pot method for the synthesis of polynitrophenols through radical tandem hydroxylation and nitration of arylboronic acids by utilizing copper(II) nitrate tri-nitydrate as the nitro source. This method features mild conditions, a simple procedure, and good functional group tolerance. Compared to conventional methods, this work provides a straightforward approach for the polynitration of aromatic compounds.
The nitration of electron-rich aromatics

The successful mononitration of a variety of electron-rich aromatic substrates is reported, employing either nitronium tetrafluoroborate or 'claycop' as the nitrating agent. Dinitration of four of the substrates was achieved when employing nitronium tetrafluoroborate. Several of the products have previously been prepared only by indirect methods.

, (2008/06/13)
A process for the preparation of nitrophenols by adding over a period of time a suspension containing from about 4 to about 20 per cent weight/volume of nitrosated phenol to a nitric acid solution containing between 45 and 100 per cent by weight of nitric acid, said solution being maintained at a temperature in the range from about 45° to 100°C.
