(57) Abstract: A compound which has a substituent group which is easily converted chemically and is highly versatile as a synthetic raw material, and which has two or more trifluoromethyl groups obtained from a low toxicity raw material. Provided are a halogen-containing perfluoropentane derivative and a method for producing the same. A 2- (trifluoromethyl) perfluoropentane derivative represented by the general formula (I): CF 3 CF 2 CF 2 C (CF 3 ) 2- X (I) (wherein X is Cl, Br, or OH). In the presence of a phase transfer catalyst, a cationic halide ion donor, acidic fluoride ion HF 2 - and 1,1,1,3,4,4,5,5,5-nonafluoro-2- A method for producing the above derivative, which comprises reacting (trifluoromethyl) -2-pentene. |
