A novel method was developed for synthesizing 2-substituted 1,3-benzothiazoles through a copper-catalyzed, one-pot, three-component reaction of a 1-iodo-2-nitrobenzene with sodium sulfide and an aldehyde. Georg Thieme Verlag Stuttgart - New York.

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.

A novel way to synthesize 2-arylbenzothiazoles is described. Reactions of benzothiazoles with diverse benzylamines in the presence of K2S 2O8 and KOt-Bu in DMSO-H2O afforded the desired 2-arylbenzothiazoles in good yields. It is notable that no transition-metal catalyst is needed in this reaction. Compared with other known methods, this method of synthesizing 2-arylbenzothiazoles can be advantageous in cases where substituted benzothiazoles and benzylamines are readily available.
