Versuchsvorschrift

A mixture of the above oxime (13.5 g, 71 mmol), 1,2-dibromoethane (65 ml), potassium carbonate (29.4 g, 213 mmol) and acetone (100 ml) was heated at reflux for 16 h and then stirred at room temperature for 7 days. The mixture was filtered and the solvent was evaporated from the filtrate in vacuo to give 20.7 g of 2,2,2-trifluoroacetophenone O-(2-bromoethyl)oxime.
