| Abstract: | Interaction of 1,1,2,3,3-pentafluoro-1,5-hexadiene with Br2 in a MeCOOH medium results in the product of selective bromination of the hydrocarbon double bond,i.e., 5,6-dibromo-1,1,2,3,3-pentafluoro-1-hexene. Epoxidation of the latter with H2O2 in an alkaline medium followed by debromination afforded 5,6-epoxy-4,4,5,6,6-pentafluoro-1-hexene for the first time.Translated fromIzvestiya Akademii Nauk.
