A series of linear and branched high-spin diand tri(cation radical)s (12•2+, 72•2+, 33•3+, 43•3+, and 93•3+) has been prepared by oxidation of the corresponding meta-para aniline oligomers. The oligo(cation radical)s are stable under ambient conditions. The formation and properties of the cation radicals has been studied in detail by cyclic voltammetry and UV-vis-near IR spectroscopy. ESR spect...
Boron/nitrogen co-doped diamond electrode for highly efficient electrochemistry detection of aniline
Aniline is a mutagenic and carcinogenic material for human health, it desirable to construct high-performance detecting system the trace detection of aniline. In this work, boron (B)/nitrogen (N)-doped diamond (BND) films prepared by chemical vapor deposition are proposed as electrochemical electrodes detect aniline in wide concentration scale. The BND have high sensitivity (detect limitation 0...
Sulfones feature prominently in biologically active molecules and are key functional groups for organic synthesis. We report a mild, photoredox-catalyzed reaction for sulfonylation of aniline derivatives with sulfinate salts, and demonstrate the utility of the method by the late-stage functionalization of drugs. Key features of the method are the straightforward generation of sulfonyl radicals ...
Oxidative polymerization of aniline in aqueous solution in the presence of trehalose was conducted. Fourier transform infrared spectroscopy confirmed successful preparation of polyaniline containing a trace amount of trehalose. Electron spin resonance spectroscopy revealed that electron spin concentration of the polyaniline increases with aniline/trehalose ratio in the polymerization. Scanning ...
In the title compound {systematic name: 4-chloro-N-[1-(1H-imidazol-1-yl)-2-propoxyethyl-idene]-2-(trifluoro-meth-yl)aniline}, C(15)H(15)ClF(3)N(3)O, the dihedral angle between the aniline and imidazole ring planes is 81.80 (4)°. In the crystal structure, weak inter-molecular C-H⋯X (X = N, O or F) hydrogen bonds and C-H⋯π inter-actions help to consolidate the packing.
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...
