摘要：
A process is disclosed for making 1,1,1,4,4,4-hexafluoro-2-butene. The process involves reacting 2,2-dichloro-1,1,1-trifluoroethane with copper in the presence of an amide solvent and 2,2′-bipyridine. A process is also disclosed for making 1,1,1,4,4,4-hexafluoro-2-butene. The process involves reacting 2,2-dichloro-1,1,1-trifluoroethane with copper in the presence of an amide solvent and a Cu(I) salt. A process is further disclosed for making 1,1,1,4,4,4-hexafluoro-2-butene. The process involves reacting 2,2-dichloro-1,1,1-trifluoroethane with copper in the presence of an amide solvent, 2,2′-bipyridine and a Cu(I) salt.
