    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.
