Compositions suitable for use as electrophilic halogenating agents and their use in the electrophilic halogenation of organic substrates

摘要

A compostions suitable for use as an electrophilic halogenating agent comprises as a first component one or more organic halogen-containing compounds or inorganic hypochlorites and as a second component an inorganic solid. A preferred inorganic solid is a crystalline or partially crystalline zeolite, for example faujasites of the X and Y types, ZSM5, large pore mordenite and zeolite L.
