In the paper,the diarylamines 4,4'-dimethyldiphenylamine and 3-methyldiphenylamine were treated respectively with 4,4'-diiodobiphenyl to afford the triarylamines N,N,N',N'-tetra(4-methylphenyl)-1,1'-biphenyl-4,4'-diamine(S-100) and N,N'-diphenyl-N,N'-di(3-methylphenyl)-1,1'-biphenyl-4,4'-diamine(m-TPD) in 93.
以4,4’-二甲基二苯胺和3-甲基二苯胺为原料分别与4,4’-二碘联苯反应合成了N,N,N’,N’-四(4-甲基苯基)-1,1’-联苯-4,4’-二胺(S-100)和N,N’-二苯基-N,N’-二(3-甲基苯基)-1,1’-联苯-4,4’-二胺(m-TPD),产品收率为93。
