실험 절차

1,1,1,2-Tetrafluoro-2-(trifluoromethyl)-pentane ((CF3)2CFCH2CH2CH3) may be prepared by reacting methyl perfluoroisobutyrate with ethyl magnesium bromide followed by hydrolysis to give 1,1,1,2-tetrafluoro-2-(trifluoromethyl)-3-pentanol. The pentanol is converted to 4,5,5,5-tetrafluoro-4-(trifluoromethyl)-2-pentene by dehydration with phosphorous pentoxide and the double bond saturated by hydrogenation over a palladium on carbon catalyst.
