Versuchsvorschrift

SeO2 (191 mg, 1.72 mmol, 4.00 equiv) was added in batches to a solution of 1,2-bis(4-fluorophenyl)ethanone (100 mg, 0.43 mmol, 1.00 equiv) in DMSO (4.5 mL). The resulting solution was allowed to react, with stirring, for 2 hrs while the temperature was maintained at 100° C. in an oil bath. The solids were filtered out and discarded.
