  摘要：

  通过用4-氯苯氧基乙腈将N-甲基-硝基吲唑类化合物进行亲核取代，可以有效地获得新的N-烷基-硝基吲哚基乙腈。所有化合物均已通过NMR和质谱技术进行了充分表征，其中一些化合物的结构还通过X射线衍射分析数据得到了证实。加入碱性阴离子后，在该系列硝基吲哚基乙腈中观察到互变异构转换，然后进行UV-Vis分光光度法和1 H-NMR滴定。阴离子官能团诱导的互变异构物质的形成得到密度泛函理论计算的支持。

  heptafluoroisopropoxylation reactions through the invention of a series of redox-active N-OCF(CF3)2 reagents. These reagents were readily prepared from the oxidative heptafluoroisopropylation of hydroxylamines with AgCF(CF3)2. The substitutions on the nitrogen atom significantly affected the properties and reactivities of N-OCF(CF3)2 reagents. Accordingly, two types of N-OCF(CF3)2 reagents including N-OCF(CF3)2

  七氟异丙基 (CF(CF 3 ) 2 ) 在药物和农用化学品中很普遍。然而，七氟异丙氧基化(OCF(CF 3 ) 2 ) 化合物在很大程度上仍未得到充分探索，这可能是由于缺乏对这些化合物的有效获取。在此，我们通过一系列具有氧化还原活性的N -OCF(CF 3 ) 2试剂的发明，公开了实用且高效的七氟异丙氧基化反应。这些试剂很容易通过羟胺与 AgCF(CF 3 ) 2的氧化七氟异丙基化反应制备. 氮原子上的取代显着影响了N -OCF(CF 3 ) 2试剂的性质和反应性。因此，两种类型的N -OCF(CF 3 ) 2试剂包括N -OCF(CF 3 ) 2邻苯二甲酰亚胺A和N -OCF(CF 3 ) 2苯并三唑鎓盐O'用作OCF(CF 3 ) 2分别为阴离子和自由基前体。该协议能够对一系列底物进行直接七氟异丙氧基化，以中等至优异的产量提供相应的产品。
