Synthese de tetrakis(perfluoroalkyl)-1,2,3,4 butadienes-1,3 par duplication des bis(perfluoroalkyl)-1,2 iodoethenes en presence de cuivre: Une nouvelle serie de transporteurs de gaz dissous pour usages biologiques

Bis 1,2-(perfluoroalkyl) iodoethenes 4 were prepared by thermal addition of 1-iodo perfluoroalcanes 2 on perfluoroalkylethynes 3. Their duplication in the presence of copper gives in good yields 1,2,3,4-tetrakis(perfluoroalkyl) 1,3-butadienes 1, designed to serve as inert oxygen carriers for biological uses.
