organic halides in the presence of KF and catalytic amounts of CuI at 80–120 °C for 3–8 h in DMF gave long-chain perfluoroalkylated compounds which are considered to be former by the insertion of CF:2into carbon-copper bonds.
在KF存在下,用有机卤化物处理XCF 2 CO 2 Me(X = Cl,Br),并在
DMF中于80–120°C催化量的CuI处理3–8 h,得到长链
全氟烷基化化合物,认为该化合物通过在碳-
铜键中插入CF:2来形成前一键。
