ELECTROCHEMICAL METHOD OF PRODUCING HALOGENATED COMPOUND CONTAINING CARBONYL GROUP Russian patent published in 2011 - IPC C25B3/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a halogenated carbonyl group-containing compound via electrochemical reaction of the corresponding carbonyl group-containing compound with a hydrogen halide H-X, an organic halide R'-X and/or a halide salt Mⁿ⁺-X_n ^- under substantially water-free conditions, wherein X is a chlorine, bromine or iodine atom, R' is an alkyl or aryl group which can be linear or branched, optionally containing one or more heteroatoms such as oxygen, nitrogen, chloride, bromide, fluoride or iodide from which the halogen atom X can be electrochemically split off, Mⁿ⁺ is a quaternary ammonium, alkali-earth metal, alkali metal or metal cation, and n is an integer ranging from 1 to 5, depending on the valence of the metal cation Mⁿ⁺.

EFFECT: method does not require additional processing of by-products formed, ensures low content of poly-halogenated by-products and easy halogenation of compounds containing a carbonyl group or hydrogen.
