Hydrochloric Acid → Benzenesulfinic acid

Participants

Reaction Steps

PhSO2Na (1.6579 g., 0.0101 mol) was dissolved in water (100 mL), while keeping an atmosphere of N2. HCl (12M, 0.84 mL, 0.0101 mol) was added in order to produce PhSO2H. Benzoquinone (0.01 mol, 1.081 g) was added while flushing with N2. A white to grey precipitate was formed immediately. The solution was stirred for 5 min, filtered (glass sinter no. 3) under N2, washed with distilled water (-20 mL) and dried under vacuum (+20° C. over night. Yield 2.08 g. The product was identified by 1H- and 13CNMR spectroscopy.
