Abstract
Two new approaches to multigram synthesis of dithieno[2,3-b:3′,2′-d]thiophene are described. Various mono-, di-, tri- and tetrabromides of dithieno[2,3-b:3′,2′-d]thiophene are prepared in good yield.
Key words
thiophenes - sulfur - heterocycles - bromine - electrophilic aromatic substitutions
