Abstract:

An efficient method for introduction of biogenic tropylium cycle into aromatic amines molecules is offered. Introduction is carried out in the presence of imidazole as a strong base. Interaction between tropylium salts (tetrafluoroborate or perchlorate) and aromatic amines with either nitro- or acetyl groups (meta-nitroaniline, para-nitroaniline, 2-methyl-4-nitroaniline and para-acetylaniline) as electron-acceptor substituents in the benzol ring results in stable products resulting from substitution of the hydrogen atom in the amino group of aromatic amines, namely: 4-nitro-N-(1'-cyclohepta-2'

In the title compound, C12H9ClN2O4S, the N—H bond in the –SO2—NH– segment issynto both theortho-nitro group in the sulfonylbenzene ring and theortho-Cl atom in the aniline ring. The molecule is twisted at the S—N bond with a torsion angle of 75.0 (2)°. The dihedral angle between the sulfonylbenzene and aniline rings is 54.97 (11)°. The amide H atom shows bifurcated hydrogen bonding, generatingS(7) andC(4) motifs. In the crystal, N—H...O(S) hydrogen bonds link the molecules into chains.

Nitro-aromatics are listed in carcinogenic, teratogenic, and mutagenic compounds list. p- nitro-aniline is one of them used as a precursor of various chemical compounds in many industries like dyes, drugs, paints and several others. These are mostly given out as an effluent in rivers, lakes or open passage of land which exert several hazards to living creatures and environment. Some of the organic compounds are stable in alkaline condition and persist longer in environment. Very few reports are elaborating bio-remediation in alkaline condition using different hydrocarbons.

2,4-Dinitro-N-(2-phenylethyl)aniline, C14H13N3O4, (I), crystallizes with one independent molecule in the asymmetric unit. The adjacent amine and nitro groups form an intramolecular N—H...O hydrogen bond. Theanticonformation about the ethyl C—C bond leads to the phenyl and aniline rings being essentially parallel. Molecules are linked into dimers by intermolecular N—H...O hydrogen bonds, such that each amine H atom participates in a three-centre interaction with two nitro O atoms. Though the dimers pack so that the arene rings of adjacent molecules are parallel, the rings are staggered and π–π

Some novel azetidinone derivatives containing aryl sulfonyloxy group have been prepared. The 4-sulfonyloxy aniline derivative (2) has been prepared by reaction of 4-nitro phenol (sodium salt) with N-acetyl sulfanilyl chloride (ASC) followed by hydrolysis by ethanolic HCl. This compound (2) undergoes facile condensation reaction with aromatic aldehydes to yield different Schiff’s bases (3a-h). Cyclocondensation of compounds (3a-h) with chloro acetyl chloride yields different 2-azetidinone derivatives (4a-h).

This paper involves the synthesis of new oxazepine derivatives by multi-reaction steps. The first step synthesis azo derivative from 2-naphthol with 3-aminoacetophenone. The second step was the condensation reaction between ketone group of the azo compound and different primary aromatic amines (4-amino phenol, 3-nitro aniline and 4-methyl aniline) to yiled new azo Schiff base compounds (S1-S3) respectively. In the final step, Oxazepine compounds (L1-L3)and (L4-L6)were prepared from reaction imine compounds (S1-S3) with maleic and phthalic anhydride in toluene as solvent. All these derivatives

Abstract:

Abstract An analysis, using CNDO wave functions, has been carried out on the different contributions to the internal rotation barrier in N-benzylideneaniline (1) and p-dimethylaminobenzylidene-p-nitro-aniline (2) in several conformations. The stability of the different structures has been expressed in terms of a partition of the total energy into electronic, net charges and steric hindrance contributions. Based on the shape of the total energy surface it appears that the barrier composition may be reasonably well described without approaching the absolute minimum. Rotation of the aniline group

Notwithstanding its simple structure, the chemistry of nitric oxide (NO) is complex. As a radical, NO is highly reactive. NO also has profound effects on the cardiovascular system. In order to regulate NO levels, direct therapeutic interventions include the development of numerous NO donors. Most of these donors release NO in a single high-concentration burst, which is deleterious.N-Nitrosated secondary amines release NO in a slow, sustained, and rate-tunable manner. Two new precursors to sustained NO-releasing materials have been characterized.N-[2-(3,4-Dimethoxyphenyl)ethyl]-2,4-dinitroanili

All complexes have low conductance value (13.6-20.6 ohm-1cm-1mol-1), indicating that they are non-electrolyte. However the cytotoxic analysis indicates that Co(II) complex was more toxic with the LC50 value of 181.72 ug/ml than
