The Pd-catalyzed tetraarylation of diamines and oxadiamines with 2,7-dibromonaphthalenes and 4,4′-dibromobiphenyl was studied. These reactions gave the corresponding N,N,N′, N′-tetra(bromoaryl) derivatives in the yields up to 50%. The product yields strongly depend on the structure of the starting diamines. The synthesized compounds were involved in the Pd-catalyzed amination with 2 equiv. of oxadiamines
研究了 Pd 催化的二胺和恶二胺与
2,7-二溴萘和
4,4'-二溴联苯的四芳基化反应。这些反应产生了相应的N,N,N ', N'-四(
溴芳基)衍
生物,产率高达 50%。产物收率很大程度上取决于起始二胺的结构。合成的化合物以 2 equiv 参与 Pd 催化的胺化反应。氧化二胺生成双大环化合物。已证明
萘基衍
生物通常产生结构异构体的混合物,即, bismacrocycles 和 macrobicycles (cryptands). 使用
萘二胺衍
生物实现了更好的大环化收率,并且大环化的净结果由两个反应分子中的恶二胺部分的结构预先确定。
