Synthesis of 2-Bromo-2′-phenyl-5,5′-thiophene: Suzuki Reaction Versus Negishi Reaction

2-Bromo-2′-phenyl-5,5′-thiophene was synthesized by cross- coupling reaction of phenylboric acid and 2,2′-dibromo-5,5′-bithiophene with a Suzuki reaction; we found the Suzuki reaction to give a higher yield when compared to the Negishi reaction.
