Application:

3-Bromothiophene can be used as a reactant to synthesize:
• 3,3-Bithiophene via borylation followed by Suzuki coupling.
• 3-Alkylthiophenes by NiDPPP⁺⁺ catalyzed cross-coupling with Grignard reagents.
• 3-Lithiothiophene by treating with n-butyllithium in hexane.
• Derivatives of thienylenic α, ω−diformyl−α−oligothiophenes.
• N-(2-(3-bromothiophen-2-yl)phenyl)methanesulfonamides by coupling at the 2-position with N-arylmethanesulfonamides, mediated by iodobenzene diacetate (178721).
