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.
Sloane, Crane, and Mayer (2) reported that Mycobacterium smegmatis oxidizes aniline to p-aminophenol. It was also shown (2) that p-aminobenzoic acid (PABA) yields p-aminophenol after the PABA is first enzymatically decarboxylated to aniline. It is the purpose of this publication to present data on the effect of pH, citrate, inorganic ions, and inhibitors on this hydroxylation reaction. The data...
The title mol-ecule, C(20)H(31)NO(8), has pseudo-C2 symmetry about the C-N bond, with the bis-(tert-butoxy-carbon-yl)amino group twisted from the benzene ring plane by ca 60° and the bulky tert-butoxy-carbonyl (Boc) groups are orientated away from the substituted aniline group. As part of an anti-bacterial drug discovery programme furnishing analogues of platensimycin, we unexpectedly synthesiz...
Methylthio moiety was observed to alter the mesomorphic features of rod-like Schiff-base-derived liquid crystalline materials. For this purpose, a new series (E)-4-(alkoxy)-N-(4-(methylthio)benzylidene)aniline (In) crystals were synthesized and examined using experimental computational approaches. The compounds in differ from each other terminal alkoxy chain length that is attached one end arom...
metal—polyaniline nanocomposites such as platinum-polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of pt+4 ions into pt nanoparticles. thepolymerization of aniline was carried out in the presence of 1(2ptcn6 [potassium hexa cyanoplatinate (iv)] as oxidizing agent. during the reaction aniline monomers undergo oxidation andform polyaniline (pant) w...
Oxidative behaviors of three toxic pollutants including aniline, p-toludine and p-chloroaniline with ClO2 in water were studied with HPLC. The removal rates of anilines were used as criteria in this experiment. Effects of the ClO 2 concentration, pH and reaction time on the removal rate of anilines were discussed. The results show that for 1mmol ·L-1 aniline, p-toludine and p-chloroaniline, the...
Three of the nine isomeric N-(nitrobenzylidene)iodoanilines, C13H9IN2O2, have been found, when crystallized from acetone, to yield polymorphs which differ from those obtained upon crystallization from ethanol. In the second polymorph of 2-iodo-N-(2-nitrobenzylidene)aniline, the molecules are disordered across inversion centres in space group C2/c, but there are no direction-specific interaction...
Novel electrically conducting composite materials consisting of poly(aniline) (PANI) nanoparticles dispersed in a poly(vinyl alcohol) (PVA)-g-poly(acrylic acid) (PAA) hydrogels were prepared within the polymer matrix by in situ polymerization of aniline. The conversion yield of aniline into PANI particles was determined gravimetrically while structural confirmation of the synthesized polymer wa...
