Arylation of diarylamines catalyzed by Ni(II)-PPh3 system

(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.

Polytriphenylamine derivative with high free radical density as the novel organic cathode for lithium ion batteries

Polytriphenylamine derivative, poly[N,N,N,N-tetraphenylphenylenediamine] (PDDP), with a high free radical density, has been synthesized and studied as a cathode material for organic free radical batteries for the first time. The chemical structure, morpho

Photochemistry of Cation Radicals in Solution: Photoinduced Electron-transfer Reactions between Alcohols and the N,N,N',N'-Tetraphenyl-p-phenylenediamine Cation Radical

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.

Electron-Catalyzed Coupling of Magnesium Amides with Aryl Iodides

An electron was found to catalyze the coupling of magnesium diarylamides with aryl iodides giving triarylamines through a radical-anion intermediate. The transformation requires no transition metal catalysts or additives, and a wide array of products are formed in good-to-excellent yields.

Synthesizing method of tetracarboxylic acid N,N,N',N'-tetra-(4'-carboxyl biphenyl)-1,4-phenylenediamine

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.

Chemoselective amination of bromoiodobenzenes with diarylamines by palladium/Xantphos or ligand-free copper catalysts

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.

Catalytic carbon-nitrogen bond-forming cross-coupling using N-trimethylsilylamines

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.
