Reaction Conditions

Reaction Steps

A round-bottom flask is charged with 50 ml of CFC-113 and 2.0 g of sodium percarbonate (13 mmoles or 19 mmoles of H2O2 equivalent). After chilling the contents of the flask to 0° C., 2.83 ml of FSO2CF2(C═O)F (25 mmoles) is added and the resulting slurry is stirred magnetically for 3 hours. The reaction mixture is filtered through a pad of Drierite® on glass wool, washing through with fresh CFC-113, an operation assumed to remove any unreacted percarbonate and any free H2O2. The filtrate, now measuring 52 ml in volume, is found to be 0.10 M in peroxide for a 42% yield based on starting FSO2CF2(C═O)F.
