Synthesis of 2-Acylbenzothiazoles via the Cu(OTf)  letter 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′-disulfanediyldianilines. A variety of different dihalidestyrenes and diphenyldisulfanes were efficiently converted into the corresponding 2-acylbenzothiszole derivatives in the presence of Cu(OTf)2. Mostimportantly, 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
