ANODIC GENERATION OF COMPOSITE HALOGEN REAGENTS AND THEIR APPLICATIONTO ORGANIC-REACTIONS

Composite iodine reagents (termed ''IB-, IC- and IF- reagents'' in thi s article, and most likely polyiodohalide ions, I(m)X(n)-) with other halogens (X: Br, Cl and F) were anodically generated by oxidation of m ixtures of GAMMA and X- ions in CH2Cl2. The oxidizing and halogenating powers of the reagents were examined in an ex-cell manner toward some model organic compounds, and were found to be precisely controlled by the amount of electricity passed and concentration ratio of X-/GAMMA used on preparing them. A composite bromine reagent with fluorine was also examined preliminarily.
