摘要:
Perfluorobutadiene and higher alkandienes, with terminal double bonds, are obtained from α,ω-dibromo or α,ω-bromo iodo perfluoroalkanes by dehalofluorination carried out at limited reaction times by means of an organometallic compound in the presence of an aprotic solvent selected from the class of hydrocarbons or a polar aprotic solvent selected from the class of ethers.
