simple approach to N,N-diphenyl carbazolium salts using only three synthetic steps, allowing for an easy production of these salts in large amounts and in a relatively short time. In addition, we study the Cu(I) catalyzed multi-arylation of 2,2’-diaminobiphenyl, focusing on the regioselectivity of each step. Finally, we characterize, for the first time, the solid state structure of a tetraaryl ammonium
四芳基铵盐是一个合成挑战,因为没有用于三芳基胺芳基化的通用方法。与其他季铵盐相反,四芳基铵盐的化学性质应该非常稳定。ipso 碳不是很亲电,因为正电荷分布在整个 pi 系统中,并且它们没有酸性 β 氢。在这里,我们展示了一种仅使用三个合成步骤的 N,N-二苯基咔唑盐的简单方法,可以在相对较短的时间内轻松地大量生产这些盐。此外,我们研究了 Cu(I) 催化的 2,2'-二氨基联苯的多芳基化,重点是每个步骤的区域选择性。最后,我们首次表征了四芳基铵盐的固态结构。
