Synthesis of 2-Acylbenzothiazoles via the Cu(OTf)2-Catalyzed tandem reaction of β,β-Dihalidestyrenes with 2,2′- Disulfanediyldianilines

A new method has been developed for the one-pot construction of 2-acylbenzothiazoles via the Cu(OTf)2-catalyzed tandem reaction of β,β-dihalidestyrenes with 2,2′-disulfane-diyldianilines. A variety of different dihalidestyrenes and diphenyldisulfanes were efficiently converted into the corresponding 2-acylbenzothiszole derivatives in the presence of Cu(OTf)2. Most importantly, this protocol allowed for the long chain 1,1-dibromohept-1-ene to be converted into the corresponding 2-hexylbenzo[d]thiazole in moderate yield.

Metal-free aerobic oxidation of benzazole derivatives

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.
