Perfluoroalkylation of benzene, halobenzenes, pyridine, furan and thiophene has been accomplished through thermolysis of perfluoroalkyl iodides (CF3I, n-C10F21I and RfORfI) in the presence of the appropriate aromaticcompound. Yields of alkylated products vary depending on temperature, presence of an HI acceptor and reactants ratio. Isomeric mixtures are obtained with halobenzenes, pyridine and thiophene
苯,卤代苯,吡啶,呋喃和噻吩的全氟烷基化是通过在适当的芳族化合物存在下对全氟烷基碘(CF 3 I,nC 10 F 21 I和R f OR f I)进行热解来实现的。烷基化产物的产率取决于温度,HI受体的存在和反应物比率而变化。与卤代苯,吡啶和噻吩得到异构体混合物。然而,呋喃仅产生α取代的产物。

The reaction between perfluoroalkyl-Grignard or lithium compounds and diethyl carbonate has been investigated. Under appropriate conditions, symmetric or asymmetric ketones can be prepared. The reactions of the perfluoro- Grignard or lithium compounds with diethyl oxalate can yield keto-esters and symmetric or asymmetric ketones.
1,1,1-Trichloro- and tribromo polyfluoroalkanes have been synthesized from perfluoroalkyl iodides and anhydrous aluminum chloride and bromide respectively. The reaction is also applicable to perfluoroalkylether iodides, though varying amounts of by-products are formed depending on the structure of the starting iodide.
