FIELD: chemistry.
SUBSTANCE: claimed invention relates to method of obtaining 3,5-bis(trifluoromethyl)benzyl alcohol which includes interaction of 3,5-bis(trifluoromethyl)phenylmafnesium halogenide with solid paraformaldehyde in solvent and hydrolysis of obtained adduct with water solution of inorganic acid, as well as to method of obtaining 3,5-bis(trifluoromethyl)benzylhalogenide by interaction of 3,5-bis(trifluoromethyl)benzyl alcohol with HX, where X represents halogen.
EFFECT: obtaining product with output comparable with output obtained using gaseous fomaldehyde, but to avoid using toxic gaseous folmaldehyde and critical conditions of work with it.
