HalogenationO 0235 Benzylic Brominations with N-Bromosuccinimide in (Trifluoromethyl)benzene.
— A simple procedure allows the bromination of mono-, di- and trimethylated arenes and hetarenes with NBS under photochemical conditions. Generally, AIBN is used as catalyst. However, the halogenation can also be carried in the presence of ACN or Bz-O-O-Bz. In the case of substrate (XII), the transformation is successful with Br2 in the absence of any catalyst. — (SUAREZ, D.; LAVAL, G.; TU, S.-M.; JIANG, D.; ROBINSON, C. L.; SCOTT, R.; GOLDING*, B.
