A procedure for oxidative halo-decarboxylation of alpha,beta-unsaturated carboxylic acids using iodosylbenzene, or iodosylbenzene diacetate, and N-chloro-, N-bromo-, or N-iodosuccinimide is presented. Good yields of the corresponding bromoalkenes are obtained when the alpha,beta-unsaturated carboxylic acids are substituted with an aromatic substituent in the beta-position and N-bromosuccinimide is used as the halogenation reagent. The scope of mainly the oxidative bromo-decarboxylation reaction is presented, and a tentative mechanism is proposed.
