(Z)-1,4-diphenyl-2-phenylamino-2-butene-1,4-dione: Synthesis and mechanizm of formation
Akimova,Trofimenko,Verbitskii,Gerasimenko
, p. 693 - 698 (2004)
Heating of 1-phenyl-2-(phenylamino)ethanone in a water-ethanol solution of potassium carbonate gave rise to (Z)-1,4-diphenyl-2-phenylamino-2-butene-1,4- dione; it formed most probably by reaction of the initial aminoketone with its oxidation product, 1-ph
Substrate-controlled and highly stereoselective synthesis of 2-aminobut-2-ene-1, 4-diones
Deng, Cong,Yang, Yan,Gao, Meng,Zhu, Yan-Ping,Wu, An-Xin,Ma, Jun-Rui,Yin, Guo-Dong
experimental part, p. 3828 - 3834 (2012/07/02)
2-Methylthio-substituted 1,4-enediones, obtained from readily available aryl methyl ketones, were reacted with primary or secondary amines to afford the desired 1,4-diaryl-2-aminobut-2-ene-1,4-diones in excellent yields with high Z/E-stereoselectivity.
Use of [hydroxy(tosyloxy)iodo]benzene in a novel and facile synthesis of 1,4-diaryl-2-(arylamino)but-2-ene-1,4-diones
Prakash, Om,Batra, Anita,Chaudhri, Vishwas,Prakash, Richa
, p. 2877 - 2878 (2007/10/03)
The reaction of acetophenones 1 with [hydroxy(tosyloxy)iodo]benzene followed by treatment of the resulting α-tosyloxyacetophenones 2 thus formed with anilines 3 in the presence of sodium carbonate in ethanol provides a novel one-pot synthesis of 1,4-diary
New reaction of mononitroarenes: Condensation with two acetophenone molecules via the nitro group
Moskalev,Tartynova,Bagryanskaya,Gatilov
, p. 462 - 464 (2007/10/03)
Nitrobenzene, p-bromonitrobenzene, N,N-diethyl-p-nitroaniline, and 9-methyl-3-nitrocarbazole undergo condensation with two moles of acetophenone in a DMSO-KOH system to form the corresponding (Z)-1,4-diphenyl-2-arylamino-2-butene-1,4-diones.
A New Reaction of Nitrobenzene: Nucleophilic Addition of Acetophenone in the DMSO-Potassium Hydroxide System to the NO2 Group with the Formation of an Enamino Ketone
Moskalev, N. V.,Tartynova, M. I.,Ogorodnikov, V. D.,Kadychagov, P. B.
, p. 785 - 786 (2007/10/02)
In the DMSO-potassium hydroxide system nitrobenzene adds 2 moles of acetophenone, forming (Z)-1,4-diphenyl-2-phenylamino-2-butene-1,4-dione.Acid hydrolysis of the latter gives aniline and 1,4-diphenylbutane-1,2,4-trione.
Reactions of aromatic nitro compounds with acetophenone in the presence of alkali. Crystal structure of (E)-1,2-dibenzoyl-o-tolylaminoethylene
Greci, Lucedio,Pieroni, Mirco,Tosi, Giorgio,Rizzoli, Corrado,Sgarabotto, Paolo,Ugozzoli, Franco
, p. 693 - 699 (2007/10/02)
Methyl and methoxy substituted nitroarenes were reacted with acethophenone in the presence of sodium ethoxide in ethanol giving arylamino-conjugated diketo derivatives.A case of ipso-substitution of a methoxy group is discussed.The title compound C23H19NO
Photochemical Transformations of (E)-1-(2'-Arylidene-1'-phenylhydrazinyl)-1,2-dibenzoylalkenes
Pratapan, S.,Scaria, P. M.,Bhattacharyya, K.,Das, P. K.,George, M. V.
, p. 1972 - 1976 (2007/10/02)
The photochemistry of several (E)-1-(2'-arylidene-1'-phenylhydrazinyl)-1,2-dibenzoylethylenes has been studied by steady-state photolysis, product analysis, and laser flash photolysis.Exhaustive photolysis in benzene and methanol gives 3-aryl-4,5-dibenzoy
Reduction of Nitroarenes to Anilines in Basic Alcoholic Media
Prato, Maurizio,Quintily, Ugo,Scorrano, Gianfranco
, p. 1419 - 1424 (2007/10/02)
Substituted nitrobenzenes are reduced by alkoxide ions in alcohols to the corresponding azoxy and aniline derivatives.The reaction leading to anilines has been investigated in detail.Two different processes have been identified, both initiated by the condensation between the nitrosoarene intermediate (the first product of the reduction reaction) and the product of oxidation of the solvent.The imino derivative thus formed (ArN=CH-COR) may either undergo hydrolysis (to aniline) or form, through a series of redox processes, compounds containing the ArNH-CO moiety.These are also hydrolysed to anilines in a slower reaction.
Synthesis, Structure, and Reactivity of 1,4-Diaryl-2-(arylamino)but-2-ene-1,4-diones
Paradisi, Cristina,Prato, Maurizio,Quintily, Ugo,Scorrano, Gianfranco
, p. 5156 - 5159 (2007/10/02)
The one-pot synthesis of the title compounds (1) is achieved by reacting acetophenones and nitrobenzenes in 2-propanol with potassium 2-propoxide.The stereochemistry of the 2-butenes has been determined to be Z from an X-ray analysis.Hydrolysis and reaction with hydrazine are reported as examples of the reactivity of the title compounds.
