The halogenating power of Br-Cl composite species (termed "BC-reagent" in this article) generated anodically from mixtures of Br- and Cl- in CH2Cl2 was examined in an ex-cell manner toward some organic compounds.The BC-reagent brominated methoxybenzenes, and the brominating power could be precisely controlled by means of the amount of electricity charged and by varying the ratio of Cl-/Br-.The power of the reagent was less controllable during the bromination of aniline.The reaction of olefins with the BC-reagent led to dibromination and bromochlorination, the product- selectivity of which could be also controlled.The theoretically calculated chemical composition of the BC-reagent agreed fairly well with the experimentally confirmed value in some cases.
