4,4′-二甲氧基三苯胺的合成及其光学性能

摘要

4,4'-Dimethoxy-dimphenylamine(l) was prepared by animation of methoxyanilide with p-methoxy-bromobenzene using Pd(dba)3/BINAP as the catalyst system. 4,4'-Dimethoxy-triphenyl-amine(2) were synthesized by C - N cross-coupling reaction of 1 with bromobenzene using Pd(dba) 3/PBut3HBF4 as the catalyst system. The structure was confirmed by 1H NMR and IR. The optical properties of 2 were investigated by UV and fluorescence spectra.%以对甲氧基溴苯和对甲氧基苯胺为单体,Pd(dba) 3/BINAP为催化体系,通过钯催化的氨化反应制得4,4′-二甲氧基二苯胺(1)；再以Pd( dba) 3/PBu3 HBF4为催化体系实现了1与溴苯的C-N交叉偶联合成4,4′-二甲氧基三苯胺(2),其结构经1H NMR和IR确证.采用UV和荧光光谱研究了2的光学性能.
