Abstract
Received January 3, 1997 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 inexpensive hydrochlorofluorocarbon 1,1,1-tri- fluoro-2,2-dichloroethane (HCFC-123) by heating it at 60 °C with metallic copper in diethylamine.1 ... We reproduced that result, but found a small but significant impurity, CF3CH2Cl, which proved very dif- ficult to separate. In an attempt to further minimize this ...
