Abstract

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).

Abstract

A convenient synthetic route to (R)-tomoxetine hydrochloride (90% ee) and (S)-fluoxetine hydrochloride (84% ee) is described. (S)-3-Phenyl-3-hydroxypropyl p-toluenesulphonate, the key intermediate, is obtained by the oxidative kinetic resolution of the corresponding racemic 3-phenyl-3-hydroxypropyl p-toluenesulphonate using (−)-sparteine/Pd(II)/O2 (1 atm) catalytic system.

6. An Exceptionally Stable Ti Superoxide Radical Ion: A Novel Heterogeneous Catalyst for the Direct Conversion of Aromatic Primary Amines to Nitro Compounds The authors are thankful to Dr. Devotta and the Director, NCL for their constant encouragement. Three of us (G.K.D., M.D.N., and I.S.A.) also thank CSIR for the award of an Senior Research Fellowship (SRF). Suggestions from the referees are highly appreciated.
