compound introduction
Reatant in the synthesis of bromodinitro compound, polymers via stille coupling. 3,4-diaminothiophene was obtained from the reduction of 2,5-dibromo-3,4-dinitrothiophene. Reatant in the synthesis of bromodinitro compound, polymers via stille coupling. 3,4-diaminothiophene was obtained from the reduction of 2,5-dibromo-3,4-dinitrothiophene. application： This monomer is useful in the Pd catalyzed Stille coupling to make conjugated thiophene oligomers or co-oligomers. The corresponding amine(s) can be obtained by subsequent reduction.
