The Chloroiodination of Deactivated Olefins with Antimony (V) Chloride-Iodine and Iodine Monochloride

Article abstract of DOI:10.1246/bcsj.53.1390

By the reactions of olefins with an equimolar mixture of SbCl5 and I2 in carbon tetrachloride, various chloroiodoalkanes are obtained in fair to good yields.This method is applicable to various deactivated olefins, the reactions of which to not proceed by the reported method using a mixture of CuCl2 and I2.Iodine monocloride can also be used for this reaction, but in this case both the yield and the regiospecificity of the products are sometimes inferior.
