2,3-Dichloro-1,1,1,4,4,4-hexafluorobut-2-ene → 1,1,1,4,4,4-Hexafluorobutane

Participants

Reaction Steps

To 1,1,1,4,4,4-hexafluoro-2,3-dichloro-2-butene (23.5 g, 0.1 mole) in 50 ml tetrahydrofuran were added sodium hydroxide (8.5 g) and as catalyst 5% by weight palladium on carbon (3 g). This mixture was hydrogenated with hydrogen at temperatures of 20 to 40° C. under pressures of 20 to 40 bar. The reaction mixture was worked up as in Example B, producing 8.0 g (75% of theory) of 1,1,1,4,4,4-hexafluorobutane.
