M. Vanderpuy, PREPARATION OF BIS(TRIFLUOROMETHYL) COMPOUNDS VIA FUNCTIONALIZATION OF 1,1,1,3,3,5,5,5-OCTAFLUOROPENTANE, Journal of organic chemistry, 62(19), 1997, pp. 6466-6468
The hydrochlorofluorocarbon CF3CH2CCl2CH2CF3 (3) was prepared from the
hydrofluorocarbon CF3CH2CF2CH2CF3, by a selective Cl-F exchange react
ion using AlCl3. Compound 3 was derivatized further to provide novel f
luorinated intermediates including CF3CH=C=CHCF3, CF3CH2C(O)CH2CF3, an
d CF3CH2CH(OH)CH2CF3.
