We have synthesized a series of 4,4′ perfluoro-alkylated bipyridine ligands[4,4′- bis(RfCH2OCH2)-2,2′-bipyridine , Rf=HC4F8(1a), HC8F16(1b), C3F7(1c) and C10F21 (1d)] by nucleophilic substitution reactions. The reaction of fluorinated alkoxide on 4,4′-bis-2,2′-bipyridine results in the systheses of these four fluorinated ligands. These reactions are high yieldings and purification is easy. The structures are analyzed by GC-MASS、NMR、FT-IR etc.
