摘要:
A process for preparing .alpha.,.omega.-dihaloperfluoroalkanes consisting in dihalogenating .alpha.,.omega.-diiodoperfluoroalkanes, or .alpha.,.omega.-chloroiodoperfluoroalkanes or .alpha.,.omega.-bromoiodoperfluoroalkanes with Cl.sub.2 or Br.sub.2.
摘要:
Perfluorobutadiene and higher perfluoroalkadienes, with terminal double bonds, are obtained from .alpha.,.omega.-diiodoperfluoroalkanes by deiodofluorination realized by using an organometallic compound, in the presence either of an aprotic solvent belonging to the class of hydrocarbons, or of an aprotic polar solvent, with short reaction times.
