  含金属和三氟甲基取代的嘧啶：生成和功能化

  摘要：

  当金属两侧有两个吸电子取代基（如三氟甲基和氯或溴）时，5-嘧啶基锂物种相当稳定。因此，在用异丙基氯化镁完成卤素/金属置换后，由 4,5-二溴-6-（三氟甲基）嘧啶和 5-溴-4-氯-6-（三氟甲基）嘧啶以高产率生产相应的 5-羧酸或丁基锂，然后羧化。当 4-氯-、2,4-二氯-和 2,4-二溴-6-（三氟甲基）嘧啶在与干冰反应之前用二异丙基氨基锂去质子化时，同样获得令人满意或优异的 5-羧酸产率. 相比之下，用丁基锂连续处理 2-bromo-4-(trifluoromethyl)pyrimidine 和 2-chloro-5-iodo-4-(trifluoromethyl)pyrimidine 得到了预期的羧酸，收率很低，甚至没有痕量的 amts。当 4-溴-6-(三氟甲基)嘧啶作为底物时，检测到酸。从两个相互竞争的机制途径中的任何一个中出现的双嘧啶的形成是一种永久性的有害副反应。[在 SciFinder

  摘要：

  NN键的形成可能为具有多种应用的各种含氮杂环化合物提供原始方法。为此，我们发现，容易获得的杂芳族胺是合适的底物，可为在非常温和的条件下在存在碘（III）试剂的情况下提供有效且创新的方法来形成NN键。该方法使合成具有荧光性质的富氮三氮杂戊烯衍生物成为可能，这是现有方法无法达到的。
