METHOD OF SYNTHESIS OF ADDUCTS OF FLUORO-CONTAINING HYDROCARBONS AND OLEFINS Russian patent published in 2002 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of adducts of fluoro-containing hydrocarbons and olefins of the formula RR¹R²CCR¹R²F or (FR¹R²CCR¹R²CH₂)₂ where R is taken among the group including CH₃, CH₂F, C₂H₄F, F(CF₂)_nCH₂CH₂ where n is a whole number from 1 to 10; each of R¹ is taken independently among the group including H, Cl, F and CF₃ and each of R² is taken independently among the group including H, F and CF₃. Process of synthesis involves interaction of saturated compound of the formula RF with olefin of the formula R¹R²C = CR¹R² in liquid medium in the presence of antimony pentafluoride as a catalyst under condition that if compound (FR¹R²CCR¹R²CH₂)₂ is synthesized then CH₃CHF₂ or FCH₂CH₂F is used as the saturated compound in the presence of anhydrous HF. EFFECT: increased yield of adducts. 15 ex
