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
