    摘要: A polyfluorinated butadiene having the formula ##EQU1## wherein n and m are integers from 1 to 10 and n=m or n.noteq.m, is prepared by reductive coupling, exemplarily with copper, of the corresponding 1,2-bis(perfluoroalkyl)iodoethylene having the formula CF.sub.3 (CF.sub.2).sub.n CH = CI--(CF.sub.2).sub.m CF.sub.3. This iodoethylene is conveniently prepared by a simple addition reaction between a perfluoroalkyl iodide and a perfluoroalkyl acetylene. The perfluoralkylated butadienes are useful as transporters of dissolved gas, particularly of oxygen as in blood substitutes.
