1,1,1 -Trichlorotrifluoroethane was added to ethylene using the catalyst system Fe/triethylphosphite, which eliminated the need for a solvent and avoided the corrosion problems inherent in CuCl-catalyzed reactions. The adduct, CF3CCl2CH2CH2Cl, was fluorinated with HF over a chromium(III) oxide catalyst. A series of alternating dehydrochlorinations and HF additions to internal C=C double bonds was proposed
使用催化剂体系Fe /亚磷酸三乙酯将1,1,1-三氯三氟乙烷添加到乙烯中,从而消除了对溶剂的需求,并避免了CuCl催化反应固有的腐蚀问题。加合物CF 3 CCl 2 CH 2 CH 2 Cl在氧化铬(III)催化剂上用HF氟化。提出了一系列交替的脱氯化氢和向内部C = C双键添加HF的方法,并通过热力学计算来支持,以解释CF 3 CF 2 CH = CH 2作为主要氟化产物的形成。中间体CF 3 CCl = CHCH 2通过在不存在HF的情况下将加合物进行脱氯化氢而干净形成的Cl被转化为4,4,4-三氟丁醇和CF 3 CCl = CHCH 2 X类型的其他化合物(X = OAc,OH,Br,I,H )。
