Structural Expansion of Dibenzo[<i>b</i>,<i>d</i>]thiophene Sulfone through Functionalization at Bay Positions

We report a synthesis of 1,9-dibromodibenzo[<i>b</i>,<i>d</i>]thiophene sulfone, which was converted to a respective dilithio intermediate. Subsequent trapping with electrophiles afforded either 1-substituted (R = CHO, B(OH)<sub>2</sub>) or 1,9-disubstituted (R =...
