  Selective Alternate Derivatization of the Hexaphenylbenzene Framework through a Thermodynamically Controlled Halogen Dance

  摘要：

  We report a practical synthetic protocol and mechanistic details for the selective alternate derivatization of the hexaphenylbenzene (HPB) framework through a thermodynamically controlled halogen dance. The stability of the alternately trilithiated species of HPB is interpreted by the through-space interaction at the ipso-carbons of the phenyl groups of the HPB framework. By using this approach, C-3-symmetric and lower-symmetric HPB derivatives possessing two or three kinds of substituents on the periphery have become easily and practically available.

  We report mesityllithium and p-(dimethylamino)phenyllithium as new valuable lithiating reagents, which realize Br/Li exchange reaction of bromoarenes at relatively high temperature in THF. With these reagents, we established the general and practical protocols for the selective alternate trilithiation of the hexaphenylbenzene framework.

  我们报道了异丁基锂和对-（二甲基氨基）苯基锂作为新的有价值的锂化试剂，它们在较高温度下在THF中实现溴芳烃的Br / Li交换反应。用这些试剂，我们建立了六苯基苯骨架选择性交替三锂化的通用和实用方案。
