Versuchsvorschrift
A stirred suspension of cyclopropyl m-tolyl ketone (16 g) and N-bromosuccinimide (17.8 g) in carbon tetrachloride (100 ml) was irradiated and heated under reflux by means of a tungsten lamp for 2 hours and cooled. The solid was filtered off and the filtrate evaporated. The residual oil was distilled under reduced pressure and the fraction distilling at 115°-130°/0.1 mm was collected.
