Efficient synthesis of benzo[1,2-b:6,5-b']dithiophene-4,5-dione (BDTD) and its chemical transformations into precursors for π-conjugated materials.

A straightforward synthesis of the fused-aromatic dione benzo[1,2-b:6,5-b']dithiophene-4,5-dione (BDTD) has been developed. This fused-aromatic dione was subjected to various chemical transformations to generate diverse molecules with potential use in π-conjugated materials for organic electronics.
