在课题研究总体方案指导下，边实践、边总结，重视积累阶段性的成果，滚动式推进课题的研究。

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.

中文摘要我们已合成出一系列在联吡啶的4，4′位置有两个氟化烷基侧链的联吡啶配位基[4，4′-bis(RfCH2OCH2)-2，2′-bipyridine ， Rf=HC4F8(1a)， HC8F16(1b)， C3F7(1c)及C10F21(1d)]，经由亲核取代反应，由4，4′-bis-2，2′-bipyridine反应而得，并具有不错的产率，其纯化也简易可行，所合成之产物并可用GC-MASS、NMR、FT-IR鉴定其化学结构。
