METHOD FOR PREPARING alpha-HYDROPOLYFLUOROALKANETHIOLS

摘要

FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of alpha-hydropolyfluoroalkanethiols. Method involves heating benzylpolyfluoroalkyl sulfides with 2-3-fold excess of phosphoric anhydride to temperature 150-180°C. Compounds are used as reagents in organic synthesis in synthesis of fluorine-containing sulfonyl chlorides, sulfoacids and other derivatives. Proposed method provides enhancing yield of end compounds and to simplify technology of the process. ^ EFFECT: improved method of synthesis. ^ 2 cl, 4 ex
