A new method for halogenation of aromatic compounds by using dimethyldioxirane and tetrabutylammonium halides

Lee, Yean-Jang,Wu, Huan-Ting,Lin, Chia-Ning

scheme or table, p. 585 - 587 (2010/04/23)

In this presentation the novel regioselective halogenation of arenes or phenols with dimethyldioxirane and Bu4NX is described. The results showed that a new, versatile and mild method can be utilized for preparation of aryl halides starting with arenes or phenols. Finally, this aryl halide forming methodology is applicable to structurally more complex flavonoids.
