Regioselective synthesis of 1-N-phenyl-4-(sulfonyl)benzene-1,2-diamine derivatives was carried out by the anodic oxidation of 2-aminodiphenylamine in a water/ethanol mixture in the presence of sulfinic acids as nucleophiles using both controlled-potential

The electrochemical dimerization of 2-aminodiphenylamine (2ADPA) has been studied. The data indicate that electrochemically generated (Z)-N-(6-iminocyclohexa-2,4-dien-1-ylidene) aniline (2ADPAox) can serve as a Michael acceptor in the reaction with starting molecular (2ADPA) form and converts to the corresponding dimer. The mechanism of dimerization has been studied using both controlled-potential coulometry and cyclic voltammetry. The anodic dimerization of 2-aminodiphenylamine has been successfully performed under constant current condition in good yield and purity in an undivided cell. Furthermore, electrochemical oxidation of 2ADPA has been studied both experimentally and theoretically to provide insight into the influence of some factors on the type of chemical reaction which follows 2ADPAox. The effect of natural charge of 2ADPAox on the reaction site was calculated using PBE/def2-SVP level of theory to identify regioselective sulfonation of 2ADPA. The results indicate that the natural charge of Michael acceptor 2ADPAox and thermodynamic stability of products lead to site-selectivity sulfonylation of 2ADPA. In addition, the sulfone products were evaluated for their in vitro antibacterial activity against two bacterial ATCC strains (Staphylococcus aureus, and Escherichia coli).

Quaternary salts of 2,3-dimethylquinoxalines 1-in some cases in the presence of the methylidene bases 2-yield, on dissolving in dimethyl sulfoxide or dimethylformamide, the dye bases 3 in a spontaneous reaction.Higher yields of 3 are obtained by oxidation of 1, 2 or 1/2 with copper(II) acetate or silver oxide.VIS. and 1H-NMR. spectra of the dyes are given.Their structural relationship to Huenig's two-step-redox systems is discussed.
