In the crystal of the title compound, C(13)H(12)ClNO(2)S, the N-H bond is anti to the meta-methyl group in the aniline ring. The C-SO(2)-NH-C torsion angle is -57.6 (2)°. The sulfonyl and aniline benzene rings are tilted relative to each other by 84.7 (1)°. The crystal structure features inversion-related dimers linked by pairs of N-H⋯O hydrogen bonds.

The conformation of the N-H bond in the structure of the title compound, C(14)H(12)ClNO, is anti to the meta-chloro substituent in the aniline ring, while the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring. The conformations of the N-H and C=O bonds are anti to each other, similar to those observed in 2-methyl-N-(3-methyl-phen-yl)benzamide (N3MP2MBA). The -NHC(=O)- group ma...

In the mol-ecular structure of the title compound, C(15)H(14)ClNO, the amide group forms dihedral angles of 15.8 (2) and 27.2 (2)°, respectively, with the benzoyl and aniline rings, while the angle between the benzoyl and aniline rings is 11.5 (1)°. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which give rise to infinite chains running along the c axis.

The kinetic study on the oxidation of aniline with oand p-methylaniline by ammonium persulfate (APS) has been carried out. The course of copolymerization was investigated by UV-vis spectroscopic method. Structural characterization was studied by FT-IR spectral analysis. The electronic spectra of the copolymers poly(aniline-co-p-toluidine) and poly(aniline-co-o-toluidine) show hypsochromic shift...

Diphenylamine (DPA) is a common contaminant at munitions-contaminated sites as well as at aniline manufacturing sites. Little is known about the biodegradation of the compound, and bacteria able to use DPA as the growth substrate have not been reported. Burkholderia sp. strain JS667 and Ralstonia sp. strain JS668 were isolated by selective enrichment from DPA-contaminated sediment. The isolates...

a simple and rapid spectrophotometric method for the determination of nitrite in water and soil preparation samples has been developed. determination of nitrite is based on diazotization of p-nitro aniline with nitrite and subsequent coupling with 4-amino-3-hydroxynaphthalene-1-sulfonic acid in hydrochloric acid. the factors affecting the reaction i.e. concentration of p-nitro aniline, concentr...

The title compound, C(10)H(7)N(5)O(2), was synthesized by the reaction of 4-nitro-aniline and 2,3-dicyano-propionic acid ethyl ester. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.

The reaction of 4-bromo-aniline, 18-crown-6, and perchloric acid in methanol yields the title compound, C(6)H(7)BrN(+)·ClO(4) (-)·C(12)H(24)O(6), in which the protonated -NH(3) (+) group forms three bifurcated N-H⋯O hydrogen bonds to the O atoms of the crown ether.

The ability of the antibacterial agent sulfameter (SMT) to form solvates is investigated. The X-ray crystal structures of sulfameter solvates have been determined to be conformational polymorphs. Both 1,4-dioxane and tetrahydrofuran form solvates with sulfameter in a 1:1 molar ratio. 4-Amino-N-(5-methoxypyrimidin-2-yl)benzenesulfonamide (polymorph III), C11H12N4O3S, (1), has two molecules of su...

The reaction of aniline (AH2) with an oxidizing agent in acidic solution gives rise to the formation of a mixture of products containing, besides a variety of oligoanilines named as Aniline Black or Polyaniline, Mauvein as a deeply purple phenazine derivative. Although this Mauvein synthesis was developed by W.H. Perkin more than 150 years ago and has opened the era of industrial dyestuff chemi...
