The title compound, C6H4Br2S, represents a versatile building block for the preparation of [pi]-conjugated redox-active thienyl oligomers and metal-mediated cross-coupling reactions. This is due to the presence of an electrochemically active thienyl heterocycle and a reactive dibromovinyl substituent, which easily undergoes dehydrobromination in the presence of n-butyllithium to afford 2-ethynylthiophene. In the molecule, the alkenyl unit and the thiophene ring are almost coplanar with an angle of 3.5 (2)° between the normals of the best planes of the thiophene ring and the vinyl moiety.
