<p>A process for producing a perfluoroalkyne compound includes an addition reaction step of adding Cl 2 , Br 2 , or I 2 to a compound shown by the formula (1) CH 3 C‰¡CR 1 to obtain a compound shown by the formula (2) CH 3 CX 2 CX 2 R 1 , a fluorination reaction step of reacting the compound shown by the formula (2) with fluorine gas to obtain a compound shown by the formula (3) CF 3 CX 2 CX 2 R 2 , and a dehalogenation reaction step of contacting the compound shown by the formula (3) with a metal or an organometallic compound to obtain a perfluoroalkyne compound shown by the formula (4) CF 3 C‰¡CR 2 . According to the present invention, a perfluoroalkyne compound can be produced at high productivity and high yield using starting raw materials which are environmentally friendly and industrially available. In the above formulas, R 1 represents a methyl group or an ethyl group, X represents Cl, Br, or I, and R 2 represents a trifluoromethyl group or a pentafluoroethyl group.</p> |
