Preferably activated arenes are halogenated, whereby bromination affords higher product yields. p-Substitution is preferred and concurring side-chain oxidation of alkylated arenes by oxone is not observed. — (SCHMIDT, R.; STOLLE*, A.; ONDRUSCHKA, B.; Green Chem. 14 (2012) 6, 1673-1679, http://dx.doi.org/10.1039/c2gc16508b ; Inst.

Aromatic Substitution in Ball Mills: Formation of Aryl Chlorides and Bromides Using Potassium Peroxomonosulfate and NaX. — Aryl chlorides and bromides are formed from arenes in a ball mill using Oxone and the corresponding sodium halide as oxidant and halogen source, respectively. Preferably activated arenes are halogenated, whereby bromination affords higher product yields. p-Substitution is preferred and concurring side-chain oxidation of alkylated arenes by oxone is not observed. — (SCHMIDT, R.; STOLLE*, A.; ONDRUSCHKA, B.; Green Chem. 14 (2012) 6, 1673-1679, http://dx.doi.org/10.1039/c2gc16508b ; Inst.
