Bis 2-aminophenyl

Hydrogenation of the dibenzoxadiazepine 1 in the presence of platinum results in ring opening with the formation of bis(2-aminophenyl) ether (4).325... 

Telluroxanthone is prepared from NajTe and the diazonium salt obtained from bis(2-aminophenyl)ketone. Owing to the low yield (2%), this is not a useful preparative procedure. ... 

Dipyridyl disulfide and bis(2-aminophenyl) disulfide do not undergo hydroxysulfenylation using Pb(OAc)4 or in the absence of a metal salt, but each reacts satisfactorily in the presence of catalytic amounts of copper(II) acetate.2... 

Phenylazophenyl tellurium chloride was reduced by sodium borohydride in boiling methanol to bis[2-aminophenyl ditellurium1. 

Bis 2-aminophenyl] Ditellurium7 A solution of 9.5 g (255 mmol) of sodium borohydride in 200 ml 1 M aqueous sodium hydroxide is gradually added to a vigorously stirred suspension of 41.5 g (100 mmol) of 2-(phenylazo)phenyl tellurium trichloride in 500 ml ethanol. When the tellurium trichloride has completely dissolved and the solution has become colorless, the solution is poured into 800 ml water. Air is blown through the mixture until no more ditellurium compound forms. The red crystals are collected by filtration, washed with water, dried, and recrystallizcd from benzene/hexane (1 1) yield 89% m.p. 99-101°. 

In addition, the amino group in bis[2-aminophenyl] ditellurium has been condensed with aromatic aldehydes9 and acylated with carboxylic acid chlorides10. The Schiff bases were recrystallized from ethanol/benzene (1 l)9.

Rg. 1. Formation of l,4-bis(benzimidazole-2-yl)benzene by FeCh-catalyzed oxidative cyclodehydrogenation of A,Af -bis(2-aminophenyl)-p-xyIenediimine in dimethylacetamide at 60 °C, monitored by electronic absoiption spectroscopy. Spectra were taken at time intervals over a period of 150 min. Curve 1(5) spectrum taken at start (on completion) of experiment... 

Benzothiazoles bearing a substituted phenyl group at C-2 can be prepared from the corresponding bis-(2-aminophenyl)disulfide (393). Treatment of (393) with an aroyl chloride affords the intermediate (394) which cyclizes to 2-arylbenzothiazoles (395) upon treatment with tin(II) chloride (Scheme 97) <93SC663>.

Kim and coworkers have reported a synthetic route to diverse heterocyclic compounds through the nucleophihc addition of P-amino carbonyl compounds 79 to 3-halo-4-methoxybenzynes 78 (Scheme 12.25) [51]. The benzyne intermediate 78 was generated from 5-(3-halo-4-methoxyphenyl)thianthrenium perchlorates 77 upon treatment with lithium diisopropylamide (LDA) in THF at reflux. P-Amino carbonyl compounds, such as P-amino ketones, esters, amides and aldehydes, all react smoothly with benzyne 78 under the reported reaction conditions. Moreover, bis(2-aminophenyl) disulfide, 2-aminophenyl benzenesulfonate...
