PROCESS FOR PREPARING FLUORINE-CONTAINING OLEFIN

The present invention provides a process for preparing a fluorine-containing olefin represented by Formula (2): R1CF=CH(R2) wherein R1 is F, H, F(CF2)n-(n is an integer ranging from 1 to 10) or H(CF2)m- (m is an integer ranging from 1 to 10) and R2 is H, F(CF2)n- (n is an integer ranging from 1 to 10) or H(CF2)m- (m is an integer ranging from 1 to 10), the process including a step of reacting a fluorine-containing alcohol represented by Formula (1): R1CF2CH(R2)OH, wherein R1 and R2are the same as above, with a reducing gas in the presence of a specific metal oxide. According to the process of the invention, a desired fluorine-containing olefin can be produced with high selectivity in a single reaction step using a fluorine-containing alcohol as a raw material.

α,α-DISUBSTITUTED POLYFLUOROALKANES

The reaction of 1,1,ω-trihydropolyfluoro-1-alkanols with triphenyldichloro- and triphenyldibromophosphorus gave 1-chloro- and 1-bromo-1,1,ω-trihydropolyfluoroalkanes.The 1,2-elimination of HF from the alkanes by the action of basic agents led to the formation of 1-chloro(bromo)-1,ω-dihydropolyfluoro-1-alkenes in the E form. 1,2-Dehalogenation (1-Br, 2-F) of the 1-bromo-1,1,ω-trihydropolyfluoroalkanes by the action of zinc made it possible to obtain the 1,1,ω-trihydropolyfluoro-1-alkenes. 1,2-Dehalogenation (1-Cl, 2-F) of the 1-chloro-1,1,ω-trihydropolyfluoroalkanes does not take place under analogous conditions.
