Abstract

In this report, we introduced Graphene oxide-iron oxide (GO-Fe3O4) nanocomposites as a heterogeneous catalyst for arylation/alkylation of benzothiazoles with aldehydes and benzylic alcohols in the presence of diisopropyl azodicarboxylate (DIAD) as an oxidant which exclusively produced 2-aryl (alkyl)-1H–benzothizoles in moderate to excellent yields. The absence of precious metals and toxic solvent, easy product isolation, and recyclability of the GO-Fe3O4 with no loss of activity are notable advantages of this method.
