Metal-free aerobic oxidation of benzazole derivatives
Dos Santos, Aurelie,El Kaim, Laurent,Grimaud, Laurence
, p. 3282 - 3287 (2013/06/05)
2-Benzyl benzothiazoles and benzimidazoles are easily oxidized under air and basic conditions to give the corresponding ketones in good yields. The use of palladium acetate as a catalyst has little effect and even gives, in some cases, much lower yields.
