Arylation of diarylamines catalyzed by Ni(II)-PPh3 system
Chen, Chen,Yang, Lian-Ming
, p. 2209 - 2211 (2005)
(Chemical Equation Presented) The cross-coupling of bromomagnesium diarylamides, generated in situ from diarylamines, with aryl bromides or iodides can be effected with a simple NiCl2(PPh3) 2-PPh3 catalyst system under relatively mild conditions. This coupling reaction is an inexpensive, convenient, and practical method, functioning as an alternative to the corresponding Pd-catalyzed or Cu-mediated process for the synthesis of triarylamines.

Photochemistry of Cation Radicals in Solution: Photoinduced Electron-transfer Reactions between Alcohols and the N,N,N',N'-Tetraphenyl-p-phenylenediamine Cation Radical
Moutet, Jean-Claude,Reverdy, Gilbert
, p. 654 - 655 (1982)
Irradiation of the N,N,N',N'-tetraphenyl-p-phenylenediamine cation radical (TPPD.+) with benzyl alcohol causes its reduction to TPPD and oxidation of the alcohol into benzaldehyde; with benzhydrol and 1-phenylethanol the corresponding symmetrical ethers are formed in a photocatalytic process in which TPPD.+ is recycled via two successive electron transfers.

Paragraph 0015; 0018; 0019, (2018/01/03)
The invention relates to a synthesizing method of tetracarboxylic acid N,N,N',N'-tetra-(4'-carboxyl biphenyl)-1,4-phenylenediamine. The synthesizing method comprises the following steps of enabling 1,4-benzene dibromide and diphenylamine to generate N,N,N',N'-tetraphenyl-1,4-phenylenediamine (A) through arylamination reaction; enabling the N,N,N',N'-tetraphenyl-1,4-phenylenediamine (A) and NBS (N-bromosuccinimide) to generate N,N,N',N'-tetra-(4-bromophenylacetone)-1,4-phenylenediamine (B); enabling the N,N,N',N'-tetra-(4-bromophenylacetone)-1,4-phenylenediamine (B) and 4-methyl boronobenzoate to generate N,N,N',N'-tetra-(4'-methoxycarbonyl biphenyl)-1,4-phenylenediamine (C); hydrolyzing the N,N,N',N'-tetra-(4'-methoxycarbonyl biphenyl)-1,4-phenylenediamine (C), so as to generate a target compound D, namely N,N,N',N'-tetra-(4'-carboxyl biphenyl)-1,4-phenylenediamine. The synthesizing method has the advantages that the poly-benzene ring aromatic tetracarboxylic acid compound not reported in literature is synthesized; the synthesizing method is simple, the cost is low, the yield rate is high, and the purity is high. The target compound is shown as a formula shown in the attached figure.

, p. 1437 - 1446 (2015/11/16)
Carbon-nitrogen bond-forming cross-coupling reaction of haloarenes with N-trimethylsilyl (TMS)-substituted secondary and primary arylamines proceeded with the aid of a palladium catalyst and a fluoride activator. Various TMS-N(aryl)2, TMS-NH(aryl), and TMS-N(alkyl)2 reacted to give the corresponding coupled products in high yields. Multi-TMS-amine nucleophiles such as N,N-(TMS)2-aniline and N,N′-Ph2-N,N′-(TMS)2-p-phenylenediamine also participated in this C-N coupling to give multiply C-N coupled products in high yields. The novel C-N cross-coupling reaction was successfully applied to C-N bond-forming polymerization. Relative rates of the cross-coupling of p-bromotoluene with N-TMS-substituted primary and secondary amines showed that N-TMS-diphenylamine reacted faster than N-TMS-N-methylaniline or N-TMS-aniline, and N-TMS-morpholine was the least reactive, indicating that the low basicity of the nitrogen nucleophile is the key for the smooth coupling.

We report the chemoselective amination of bromoiodobenzenes with diarylamines by palladium/Xantphos or a ligand-free copper catalyst. The reactions by these two types of catalysts proceeded with a high chemoselectivity and afforded monobrominated triarylamines in good yields. These products are useful intermediates for the synthesis of unsymmetrical bistriarylamines.
