What is 4-bromo-2,1,3-benzothiadiazole?

The Uses of 4-bromo-2,1,3-benzothiadiazole

The Sonogashira cross-coupling reaction between 4-bromo-2, 1,3-benzothiadiazole, and the respective para-substituted phenylethynyl derivatives could synthesize the BTDs. In addition, the BTD-Ph is prepared by reacting 4-bromo-2,1,3-benzothiadiazole (Br-BTD)and palladium-MAI catalyst, and the dynamic phenylboronic acid reagent in the starting system or dynamic o-amino pyridine reagent[1-2].
