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。
