Title£ºSelective and mild oxidation of suldes to sulfoxides by H2O2 using DBUH-Br3 as catalyst abstract£ºDBUH-Br3 catalyzed selective conversion of suldes to sulfoxides in the presence of H2O2 as oxidizing agent is described. The reaction was performed selectively at room temperature and relatively short reaction times. Experimental:All chemicals were purchased from Merck and Fluka chemical companies. The oxidation products were characterized by comparison of their spectral and physical data with authentic samples. [ Last edited by ½õæ on 2011-5-28 at 09:50 ] |
