Pair work organization

In this work, an attempt to planarize 2,3,4,6- tetraarylthieno[3,2-b]thiophene based on the FeCl3 oxidative annulation was described. Thus, two cyclized 2,3,5,6-tetraarylthieno[3,2-b]thiophenes 5a and 5b were synthesized in moderate yields. NMR and HR-MS analysis indicated the annulation between only one pair of the phenyl substituents.
