FIELD: chemistry.
SUBSTANCE: method includes obtaining trimethylsilyl ether or bis-trimethylsilyl ether from respective fluorine-containing mono- or bi-basic aromatic acid by its interaction with trimethylchlorosilane, its conversion into respective zinc derivative resulting from reaction with zinc salt or zinc oxide in polar aprotic solvent, such as dimethylformamide, dimethylacetamide, acetonitrile, N-methylpyrollidone, oxidation of obtained zinc derivative in the same solvent with peroxy compoubd in presence of salts of monovalent copper CuX, where X=Cl, Br, I, and further processing with concentrated hydrochloric acid, after which target mono- or dihtdroxypolyfluorobenzene is separated by known methods.
EFFECT: method makes it possible to obtain target compounds with outputs.
