Synthesis of 3,4-bis (4'-methylphenyl) thieno [2,3-b]thiophene: First example of peri-diaryl thienothiophene

Article abstract of DOI:10.1080/00397910008087211

3,4-bis(4'-methylphenyl) thienothiophene, the first example of peri- (3,4) diaryl thienothiophene has been synthesized by a sequence involving preparation of ketene dithioacetal, Dieckmann type cyclization, ester hydrolysis and decarboxylation.
