The present invention provides a novel polycyclic aromatic compound having a plurality of aromatic rings linked by a boron atom, a nitrogen atom, and the like, and thus increases the number of alternatives of a material for an organic electroluminescent (

Nickel-catalyzed synthesis of diarylamines via oxidatively induced C-N bond formation at room temperature

A nickel-catalyzed oxidative coupling of zinc amides with organomagnesium compounds selectively produces diarylamines under mild reaction conditions, with tolerance for chloride, bromide, hydroxyl, ester, and ketone groups. A diamine is bis-monoarylated. A bromoaniline undergoes N-arylation followed by Kumada-Tamao-Corriu coupling in one pot. The reaction may proceed via oxidatively induced reductive elimination of a nickel species.

Nickel(0)/N-heterocyclic carbene complexes catalysed arylation of aromatic diamines

Nickel complexes of N-heterocyclic carbenes were examined for effecting C-N coupling reactions between aromatic diamines and aryl chlorides of varying electron density. The Ni(0) ? 2IPr (IPr = N,N′-bis(2,6- diisopropylphenyl)imidazol-2-ylidene) complex associated to t-BuONa allowed N,N′-diarylation at 100 °C in 1,4-dioxane with excellent yields. Selective monoarylation of diamines could be performed in THF at 65 °C.

A new method for the selective amination of 1,3- and 1,4-dinitrobenzenes and protected nitroanilines leading to polyfunctional 1,3- and 1,4-disubstituted anilines

The addition of functionalized arylmagnesium reagents to dinitrobenzenes and protected nitroanilines at -20°C in THF furnishes after a reductive workup polyfunctional diarylamines in 47-92% yield.

On attempted oxidative cyclisation of isomeric N,N'-diphenylphenylenediamines and their N,N'-dimethyl derivatives by palladium(II) acetate and UV light

The cyclisation of N,N'-diphenyl-o-, m- and p-phenylenediamines and their N,N'-dimethyl derivatives by palladium(II) acetate and UV light separately led to both bis-cyclisation, furnishing indolocarbazoles, and mono-cyclisations with cleavage as well as retention of one substituent, producing substituted carbazoles.

Preparation and characterization of novel DPPH-based diradicals

A series of 1,1'(2,4-di-X-benzene-1,3-diyl)bis[1-(4-Y-phenyl)-2- picrylhydrazine]s were prepared an oxidized to generate the corresponding bis-DPPH diradicals. No triplet species was observed for the compounds with X = H in the ESR measurement. Modification of the central benzene ring (x = Me) and N-phenyl group (Y = OMe, P, t-Bu) allowed the detection of their triplet diradicals. Especially, the diradical with X = Me, Y = t-Bu was successfully purified, isolated at O aC as a purple solid, and was shown to be in a triplet ground state.

Synthesis of oligo(m-aniline)

Phenyl-capped dimer, trimer, and tetramer of poly(m-aniline) have been synthesized. Cyclic voltammetry has proved that the donor ability of these oligomers can be changed according to their length or topology.

Process for producing diphenylamines or N,N'-diphenyl-phenylenediamines

Diphenylamines or N,N'-diphenyl-phenylenediamines can be obtained by heat-reacting an aniline or a phenylenediamine with preferably an excess of a phenol in an amount of 4 to 20 moles per mole of the aniline or phenylenediamine in the presence of a hydrogen transfer catalyst and a cyclohexanone corresponding to said phenol. The excess phenol used in the reaction undergoes reduction in the reaction system to form a cyclohexanone, which in turn reacts with the aniline or phenylenediamine to form a Schiff base and is thus consumed. The Schiff base forms the intended product by means of a dehydrogenation reaction, and the hydrogen evolved at this time reduces the phenol to form a cyclohexanone. The phenol present in excess thus becomes in the system a solvent, a starting material for the cyclohexanone, and an acceptor of the hydrogen that forms as a by-product at the time of formation of the intended product. Hence, it becomes possible to obtain the intended product at a high selectivity from the anilines and phenylenediamines. The process of this invention is an advantageous process for the industrial production of especially the nuclearly substituted diphenylamines.

REACTION OF SODIUM SALTS OF AROMATIC SULFONIC ACIDS WITH ALKALI-METAL ARYLIDES

In the reaction of the sodium salts of benzenesulfonic acid, 1-naphthalenesulfonic acid, and 2-methyl-6-naphthalenesulfonic acid with alkali-metal arylides the sulfo groups are substituted by arylamino groups, and diphenylamine, N-phenyl-1-naphthylamine, N-(p-tolyl)-2-naphthylamine, 2-methyl-N-phenyl-6-naphthylamine, and dinaphthylamine are formed.In the reaction of disodium salts of aromatic disulfonic acids with sodium anilide substitution of the sulfo groups by arylamino groups gave N,N'-diphenyl-m-phenylenediamine, N,N'-diphenyl-p-phenylenediamine, and N,N'-diphenyl-2,6-naphthylenediamine.
