Process for the synthesis of hexafluorobutadiene and of higher perfluorinated dienes

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.
