intermolecular oxidative annulation of N-arylthio phthalimide derivatives with alkynes is showcased at room temperature. The annulation involves oxidative cleavage of the SN bond and the occurrence of 1,2-S-migration, which eventually allows the construction of diverse arrays of -conjugated 6-substituted 2,3-diaryl benzo[b]thiophene derivatives.
