RESUMO
A matrix-bound superoxide radical anion, generated by treating Ti(OR)4 (R=iPr, nBu) with H2 O2 , is a selective heterogeneous catalyst for the oxidation of anilines to the corresponding nitroarenes with 50 % aqueous H2 O2 [Eq. (1)]. Yields of 82-98 % are obtained, even with anilines bearing electron-withdrawing substituents (R=NO2 , COOH).
