Procedure

A solution of bis(trifluoroacetyl) peroxide in trifluoroacetic acid was prepared by addition of freshly distilled bis(trifluoroacetic) anhydride (21 g, 100 mmol) dropwise into a well-stirred solution of potassium trifluoroacetate (6.8 mg, 0.045 mmol) in trifluoroperacetic acid (13 g, 100 mmol) and trifluoroacetic acid (15.9 g, 139.5 mmol) at 0° C. A 29.5% (mol) solution of bis(trifluoroacetyl) peroxide in the trifluoroacetic acid was obtained.
