Description and Uses

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).
