Effective modulation of the photoluminescence properties of 2,1,3-benzothiadiazoles and 2,1,3-benzoselenadiazoles by Pd-catalyzed C–H bond arylations

A one step procedure towards the synthesis of 4-aryl-2,1,3-benzothiadiazoles and 4-aryl-2,1,3-benzoselenadiazoles using Pd-catalyzed C–H bond arylations was developed.
