Synthesis of functionalized long-chain perfluoroalkanes from methyl halodifluoroacetates: a process of difluorocarbene insertion intocopper-carbon bonds
Abstract Treatment of XCF 2 CO 2 Me (X= Cl, Br) with 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: 2 into carbon-copper bonds.
