Heteroarenes are important structural moieties in many chemical industry fields. A highly efficient Pd/Cu-catalyzed C-H arylation method for a range of heterocycles has been discovered. It was found that the key to the success of this transformation is a combination of a palladiumcatalyst and a well-defined copper cocatalyst. The efficiency and lowloadings of catalyst (0.25 mol %) and cocatalyst
The present paper describes the synthesis, the non-linearoptical and redox properties of 6-nitro-6′-piperidyl-2,2′-bisbenzothiazole, the first described member of a new family of push–pull structures based in the 2,2′-bisbenzothiazole.
