Benzothiophene 1,1-dioxide → 2,3-Dihydro-1lambda6-benzothiophene-1,1-dione

Participants

Reaction Steps

In a Parr shaker bottle was placed benzo[b]thiophene 1,1-dioxide (5.0 g, 30.08 mmol), palladium on activated carbon (500 mg) and ethanol (100 mL). The bottle was placed on a Parr shaker and charged with 50 psi of hydrogen for 1 h. The reaction mixture was removed from the Parr shaker and filtered through a plug of celite and concentrated in vacuo to afford 2,3-dihydro-benzo[b]thiophene 1,1-dioxide (5.06 g, 100%) as a white solid.
