Abstract
Alkyl, cycloalkyl or aralkyl halides may be alkylated by treatment with an olefin in the presence of a catalyst comprising a free-radical generating compound such as an organic peroxide and also in the presence of a promoter comprising hydrogen chloride, said alkylation reaction being effected at temperatures at least as high as the decomposition temperature of the free-radical generating compound, to prepare alkylated halide-containing compounds.
