Ullmann reaction of picryl bromide in the presence of ultrasound

Article abstract of DOI:10.1080/00397919108020824

Ultrasonic irradiation was found to promote the Ullman coupling of picryl bromide at or below room temperature. In the presence of excess copper, a long-lived intermediate is formed that is quenched upon work-up affording variable mixtures of trinitrobenzene and picric acid.
