In this paper, N-arylations between two heteroaryl compounds were studied. Conditions were found to generate selectively either 3- or 5-heteroarylamino-1,2,4-triazines by investigating anionic processes (use of bases such as 2,2‘,6,6‘-tetramethylpiperidine/tBuOK/nBuLi) or Pd-catalyzed N-arylations [Pd(OAc)2, xantphos]. These methods were successfully applied to a wide variety of heteroarylamines and
本文研究了两个杂芳基化合物之间的N-芳基化作用。通过研究阴离子过程(使用碱,例如2,2',6,6'-四甲基哌啶/ t BuOK / n BuLi)发现条件可选择性生成3-或5-杂芳基氨基-1,2,4-三嗪。Pd催化的N-芳基化[Pd(OAc)2,xantphos]。这些方法已成功应用于多种杂芳基胺,使我们能够继续进行熔融多氮化合物合成的研究。
