A series of new anilides (2a–c, 4–7, 17a–c, 18) and quinolones (3a–b, 8a–b, 9a–b, 10–15, 19) with nitrogen-bearing substituents from benzo[b]thiophene and thieno[2,3-c]thiophene series are prepared. Benzo[b]thieno[2,3-c]- and thieno[3′,2′:4,5]thieno[2,3-c]quinolones (3a–b, 8a–b) are synthesized by the reaction of photochemical dehydrohalogenation from corresponding anilides.
