Procedure

The compound was prepared in analogy to W. Steglich et al., Chem. Ber., 107:1488-1498 (1974). Anhydrous hexafluoroacetone (HFA) was prepared by adding HFA trihydrate dropwise to concentrated sulfuric acid heated to 80° C. The resulting gas was once more washed with concentrated sulfuric acid and then passed into the gas space of the reaction flask. A reflux condenser packed with acetone/dry ice was fitted on the gas outlet of the flask.
