    Best yields are achieved with N-bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. In a typical setup a stoichiometric amount of N-bromosuccinimide solution and a small quantity of initiator are added to a solution of the substrate in CCl 4, and the reaction mixture is stirred and heated to the boiling point.. Initiation of the reaction is indicated by more .

    N-Bromosuccinimide (30g) is purified by dissolving rapidly in 300mL of boiling water and filtering through a fluted filter paper into a flask immersed in an ice bath, and left for 2hours. The crystals are filtered off, washed thoroughly with ca 100mL of ice-cold water and drained on a Büchner funnel before drying under vacuun over P2O5 or CaCl2 [Dauben & McCoy J Am Chem Soc 81 4863 1959].
