of 2-fluoropyrazine allowed the synthesis of various 5- and 6-iodofluoropyrazines. Use of cross-coupling reactions with iodofluoropyrazines under Suzuki or Negishi conditions led to aryl and alkylfluoropyrazines. The benzylfluoropyrazines have been used as building block to synthesize a wide range of arylbenzylfluoropyrazines which could exhibit mesomorphic properties.
2-氟吡嗪的区域选择性金属化使得可以合成各种5-和6-碘氟吡嗪。在Suzuki或Negishi条件下使用与碘氟吡嗪的交叉偶联反应可生成芳基和烷基氟吡嗪。苄基氟吡嗪已被用作构建各种合成芳构型芳基苄基氟吡嗪的基础材料。
