Direct (Het)Arylation of Fluorinated Benzothiadiazoles and Benzotriazole with (Het)Aryl Iodides

Abstract

A new and controllable method for the preparation of unsymmetrical and symmetrical fluorinated benzothiadiazole (FBT)–arene structures that can be applied in organic optoelectronic materials has been developed. The reaction proceeds under mild reaction conditions with high efficiency and shows excellent functional group compatibility, even toward bromide. Fluorinated benzotriazoles also take part in the reaction
