Olefins can be halogenated in the allylic position by number of reagents of which N-bromo succinimide (NBS) is the most common. When this reagent is used the reaction is known as WohlZiegler bromination. Other N-bromoamides have also been used. To a much lesser extent allylic chlorination has been carried out with N-chloro-succinimide. N-Chloro-N-cyclohexyl benzene sulphonamide or t-hypochlorite when the allylic radical intermediate is unsymmetrical allylic rearrangement takes place so that the mixture of both possible products is obtained.
