R-Brominated alkylbenzenes are a valuable class of compounds in organic synthesis, since they are frequently used as the starting materials for synthesis of a wide variety of important compounds. R-Bromination of alkylbenzenes is usually performed by the use of bromine, 1 NBS, 2 CBrCl3, 3 CuBr2, 4 and Br-/CAN5 under heating or irradiation of light. To achieve the bromination by these reagents in satisfactory yields, the reaction must be carried out in ...
