Abstract:

Certain chemical pollutants in the environment can change a variety of biological processes. Anilines are widely used in the manufacturing of plants, colours, medications, pesticides, and herbicides. This review aims to highlight the destructive, dangerous and altering effects of aniline on various organisms. We believe that this study will provide helpful information regarding aniline's toxicological research, which will help in the formulation of acceptable guidelines for aniline usage.

Abstract:

The photophysical and photochemical behavior of several aniline spacer - styrene molecules in which the spacer is a short polymethylene chain has been investigated. Long wavelength excitation selectively excites the aniline chromophore which undergoes intramolecular quenching by the styrene to yield an intramolecular exciplex. Exciplex fluorescence is observed for both of the tertiary anilines investigated and for one of the three secondary anilines. More rapid exciplex formation in nonpolar vs. polar solvents is attributed to the necessity of desolvating the polar aniline singlet in polar sol

Abstract:

It is known that the biochemical enzymatic reaction of the reversible transfer of an amino group from an amino-acid to a keto-acid is called a transamination reaction. However, the transamination reaction is applicable not only for biochemical enzymatic reactions, but is also often used in organic synthesis to produce aromatic azomethines. As objects of study in the transamination reaction, we selected substituted N-benzylidenanilines (imines, Schiff bases) and anilines, containing a biologically active heterocyclic fragment in the para-position of the aniline ring. We have shown the feasibili

The polybutoxytitanates catalysis of aniline acylation by orthosubstituted benzoic acids leads to the production of substituted benzanilides.

The current study describes the synthesis and characterization of poly (anilineco-metanitroaniline) using different mineral acids. Poly (aniline co-meta nitro aniline) was created at room temperature using the chemical oxidative polymerization of monomer aniline and co-monomer meta nitro aniline. As a dopant, hydrochloric acid, sulfuric acid, and perchloric acid were utilized, coupled with acrylic acid as a soft templet. Analytical techniques such as FTIR, UV- DRS, and XRD were used to analyze the synthesized Poly (aniline co - Meta nitro aniline).

Abstract:

Although the history of polyaniline has been traced back to the 1834 contributions of F. F. Runge in Germany, Carl Fritzsche independently discovered an organic base via the decomposition of indigo in 1840. Fritzsche named the base anilin after the Spanish name of indigo, a name which has been retained into the present. Following his isolation of aniline, Fritzsche went on to study its oxidation products, the results of which are consistent with our modern understanding of polyaniline species. Two years after Fritzsche's isolation of aniline, Nikolay Zinin reduced nitrobenzene to give a specie

Abstract:

The gas phase acidity of anilinium ions has been calculated at a number of theoretical levels from B3LYP/6-311++G** to MP2 and CCSD/6-311++G(2dp,2pd). The highest level calculations find anilinium ion and p-protonated aniline to have essentially the same energy, in agreement with experimental studies. They also give a proton affinity for aniline that is in very good agreement with the experimental value. The B3LYP and MP2 calculations are less successful, with B3LYP favoring p-protonation and MP2 favoring N-protonation for aniline. Despite this difficulty, the calculated effect of substituents

Abstract:

The catalytic preparation of substituted benzanilides by the reaction of substituted benzoic acids with aniline is an important model process that has been intensively developed recently, in the field of the «green chemistry» concept, direct catalytic amidation, and its study is an urgent scientific and practical task. Within the framework of solving this problem, the catalysis of the acylation of aniline by substituted benzoic acids with trivalent phosphorus compounds P(III) was studied. It was established that P(III) in the amount of only 2% mol. from substituted benzoic acid effecti

Abstract:

Chlorine-containing condensing agents (PCl3, TiCl4, SiCl4) are widely used in the synthesis of carboxylic acid arylamides by the reaction of arylamines with carboxylic acids in stoichiometric amounts, and often in excess (40–150 mol % relative to the latter). To find the optimal amount of the condensing agent used, the acylation of aniline with 3-hydroxy-2-naphthoic acid in boiling ortho-xylene was studied in the PCl3 concentration range of 0–10 mol % from 3-hydroxy-2-naphthoic acid. It has been established that phosphorus tri-chlorochloride plays the role of a condensing agent and a catalyst,

Abstract:

Oxidation of aniline in aqueous solution by ·OH radicals proceeds predominantly via addition to the ring followed by elimination of OH- on the microsecond time scale to form the aniline radical cation. Direct oxidation by electron transfer accounts for less than 4% of the ·OH reactions. The different hydroxycyclohexadienyl isomers produced by ·OH addition decay at different rates with this decay catalyzed both by protons and phosphate. In basic solution the resultant radical cation deprotonates to form the anilino radical. The p Ka for the equilibrium between the acidic and basic forms of this

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:

Three general routes for the synthesis of (E)-2-alkenyl-tethered anilines have been developed. The first route involves a 3-aza-Cope rearrangement of N-allylic anilines in the presence of a Lewis acid. The requisite N-allylic anilines were prepared by the addition of vinylmagnesium reagents to the corresponding aldimines. The second route details a direct cross-metathesis of 2-allylic or 2-homoallylic anilines with styrenes. The third route involves a palladium-catalyzed C–N cross-coupling of aryl halides. Taken together, these three strategies allowed access to the requisite aniline substrate

Abstract:

1,2,4,6-Tetraaryl-1,4-dihydropyridines were obtained by the one-pot reaction of chalcones and substituted anilines on the surface of Bi(III)nitrate-Al2O3. The reaction seems to proceed via β-oxygenation of Bi(III) enolised chalcones followed by Michael addition and heteroannulation with simultaneous retro aldol disproportionation. The presence of the ring-activating groups at ortho and para positions in the aniline seems to be essential for the reaction.Key words: 1,2,4,6-tetraryl-1,4-dihydropyridines, chalcones, substituted anilines, Bi(III) nitrate-alumina catalyst.
