Abstract
Catalytic aromatic amination was achieved in water under heterogeneous conditions by the use of palladium complexes anchored to the amphiphilic PS-PEG resin with little palladium leaching to provide a green and clean (metal-uncontaminated) protocol for the preparation of triarylamines, including the optoelectronically active N,N,N',N'-tetraaryl-1,1'-biphenyl-4,4'-diamines (TPDs).
摘要
通过使用固载在两亲性 PS-PEG 树脂上的钯配合物实现了非均相条件下的催化芳香胺化反应，几乎没有钯浸出，为制备三芳基胺（包括光电活性的 N,N,N',N'-四芳基-1,1'-联苯-4,4'-二胺（TPD））提供了一种绿色、清洁（无金属污染）的方法。
