A new and controllable method for the preparation of unsymmetrical and symmetrical fluorinatedbenzothiadiazole (FBT)–arene structures that can be applied in organic optoelectronicmaterials 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
An unprecedented example for the selective synthesis of an FBT–thiophene structural motif via dual C–H functionalization, catalyzed by palladium, has been developed.
