Abstract:

Molar excess volumes and molar excess enthalpies for various (i + j) binary methylene bromide (i) + aniline or N-methyl aniline and + N,N-dimethyl aniline (j) mixtures have been determined as a function of composition at 308.15 K. The data have been analysed in terms of the graph-theoretical approach and Sanchez and Lacombe theory. The graph-theoretical analyses of VE data suggest that aniline, N-methyl aniline, and N,N-dimethyl aniline exist as equilibrium mixtures of monomer and dimer and that these mixtures contain 1:1 molecular complexes. The IR studies lend further credence to the nature

Abstract:

The copper-catalyzed reaction of 1,1-dimethyl-O-propargyl aniline carbamates was studied and revealed the unexpected formation of oxazolidin-2-ones and alkylamines. An in-depth study of the reaction conditions showed that the formation of these products was highly dependent on the solvent, copper catalyst and aniline substituents. The reaction can be oriented towards oxazolidinones in pyridine and alkylamines in ethanol, whereas cycloaddition can be achieved in dry tetrahydrofuran.

Solvent-free aminocarbonylation (Heck carbonylation) of aryl halide, catalyzed by μ-dichloro-bis(benzylidene aniline)palladium(II) complex yields dimethyl benzamide and their substitutes, has several useful industrial applications.

Bromobenzene along with more electron-rich aryl bromide generally undergo these reactions very smoothly, but the yield of respective products is less.

Abstract:

Tri(tert-butyl)plumbyl-amine 1 was prepared and studied by one- (1D) and two-dimensional (2D) 1H, 13C, 15N and 207Pb NMR which allowed determination of the coupling signs 1J(207Pb,13C) (> 0), 2J(207Pb,13C) (> 0), 1J(207Pb,15N) (> 0; reduced coupling constant 1K(207Pb,I5N) < 0) and 2J(207Pb-N-1H) (< 0). Transamination of 1 with aniline and pyrazole afforded the corresponding aniline (2) and pyrazole derivatives (3), respectively. N-Lithiation of 1, followed by treatment with Me3SiCl gave the tri(tert-butyl)plumbyl-trimethylsilyl-amine 5. The multinuclear magnetic resonance data o

The reaction of 1-R-6,6-dimethyl-5,6-dihydrobenzo[ f ]pyrrolo[2,1- a ]isoquinoline-8,9-diones (R = H, morpholinocarbonyl) with ammonia, morpholine, aniline and 1-naphtylamine proceeds with opening of dioxopyrroline cycle and forming enaminoketoamides. The conditions of reaction depends on the nature of nucleophile: ammonia and morpholine readily react at 20°C, the reaction with aromatic amines requires reflux in glacial acetic acid.

Poly(aniline-co-o-bromoaniline) (p(an-co-o-BrAn)) copolymer has been synthesized using chemical oxidation method in the hydrochloric acid medium. Copolymerization of aniline with o-bromoaniline of different compositions, such as 1:1, 1:2, 2:1, 1:3 and 3:1 molar ratios were prepared. The synthesized copolymer is soluble in polar solvents like dimethyl sulphoxide (DMSO), dimethyl formamide (DMF), Tetrahydrofuran (THF) and 1-methyl 2-pyrrolidone (NMP). The copolymer is analyzed by various characterization techniques, such as FTIR, UV–Visible (UV–Vis) spectroscopy, X-ray diffraction (XRD), conduct

Abstract:

In this study, a small organic compound containing cyano and N,N-dimethyl aniline as acceptor and donor groups, respectively linked through the conjugate system, were synthesized. Then, its structure was confirmed by FT-IR spectroscopy. Next, in order to investigate the photovoltaic properties of these organic molecules, it was tested in the fabrication of organic photovoltaic solar cells (OPVSCs). The organic solar cell with FTO/TiO2/dye molecules/electrolyte/Pt electrode configuration was constructed.

Abstract:

The reaction of ethyl 2,4,6-trinitrophenyl ether with aniline in dimethyl sulfoxide containing Dabco occurs in two stages. The first gives 5, the σ -adduct intermediate on the substitution pathway, which has been identified spectroscopically. The second yields 2,4,6-trinitrodiphenylamine, the substitution product. Kinetic studies show that proton transfer is rate limiting both in the formation of the intermediate and in its subsequent acid-catalysed decomposition. Phenoxide is a considerably better leaving group than ethoxide and the substitution reactions of phenyl 2,4,6-trinitrophenyl ethers

Abstract:

5-Phenyl-1,3,4-thiadiazole-2-amine has been synthesized by single step reaction. A series of heterocyclic azodyes were synthesized by diazotisation of 5-phenyl-1,3,4-thiadiazole-2-amine by nitrosyl sulphuric acid followed by coupling with different coupling compounds such as 8-hydroxyquinoline, 2,6-diaminopyridine, 2-naphthol, N,N-dimethyl aniline, resorcinol, and 4,6-dihydroxypyrimidine. The dyes were characterized by UV-Vis, IR, 1H-NMR, 13C NMR, and elemental analysis. The synthesized compounds were also screened for biological activity.

The kinetics of the reaction between para-substituted anilines and dimethyl acetylenedicarboxylate (DMAD) with derivatives of benzaldehyde for the one-pot formation of 3,4,5-substituted furan-2(5 H)-ones in the presence of lactic acid as a catalyst have been studied spectrophotometrically at different temperatures. A mechanism involving four steps was proposed for the reactions, all of which followed second-order kinetics. The partial orders with respect to substituted aniline and DMAD were one and one and the reactions revealed zero-order kinetics for benzaldehyde and its derivatives. Changin
