ChemInform Abstract: PHOTOCATALYZED OXIDATION OF ANILINE BY ZINC OXIDE

Increasing the index of covalent oxygen bonding at nitrogen attached to carbon

“…(no other product was described). 313 It was claimed that a superoxide anion was generated by a transfer of an electron from zinc oxide to an oxygen molecule. Interaction of aniline with the superoxide anion was considered to produce anilino radicals, perhaps via an anilino hydroperoxide.…”

Vanadia-catalyzed solar photooxidation of aniline

“…An air-equilibrated solution of aniline yields azobenzene on irradiation at 365 nm with benzophenone sensitizing the oxidation [7][8][9]. Aniline is oxidized to azobenzene on ZnO with UV light [10][11][12] and photomineralized on TiO 2 [13]. limit of 50,000 lux.…”

Self-induced nonequivalence in the association of D- and L-amino acid derivatives

“…For a mixture of the enantiomers and Sd, possible binary association equilibria are given as eq 1-3, where and SdSd Si + St ^S,S, (1) s, + sd -S,Sd…”

“…When the binary associations occur under conditions of fast interassociate exchange and a chemical shift of the sensor nuclei in the homochiral dimer is different from that in the heterochiral dimer, two NMR signals due to the enantiomers can be obtained, one corresponding to the weighted average of the three signals from Sj, S|Sd, and S¡S| and the other corresponding to the weighted average of the three signals from Sd, S|Sd, and SdSd. Thus, the chemical shift nonequivalence (1) TV-Acetyl-L-valine ierf-butyl ester, [a] lsD -29.9°( c 1.00, ethanol) and its D enantiomer, [a]18D +29.6°( c 1.03, ethanol).…”
