1,1-bis(dimethylamino)-2,2,2-trifluoroethane, a readily-available precursor to the novel fluorinated building block 1,1-bis(dimethylamino)-2,2-difluoroethene

摘要

In 1994, Aoyama reported in a Daikin patent the facile synthesis of 1,1,1,4,4,4-hexafluoro-2-butene (HFC-356mff) from the inexpecnisve hydrochlorofluorocarbon 1,1,1-tri- fluoro-2,2-dichloroethane (HCFC-123) by heating it at 60 deg C with metallic copper in diethylamine.
