Preparation of Bis(trifluoromethyl) Compounds via Functionalization of 1,1,1,3,3,5,5,5-Octafluoropentane
摘要:
The hydrochlorofluorocarbon CF3CH2CCl2CH2CF3 (3) was prepared from the hydrofluorocarbon CF3CH2CF2CH2CF3, by a selective Cl-F exchange reaction using AlCl3. Compound 3 was derivatized further to provide novel fluorinated intermediates including CF3CH=C=CHCF3, CF3CH2C(O)CH2CF3, and CF3CH2CH(OH)CH2CF3.
