Versuchsvorschrift

Cyclobutylcarbonyl chloride (23.8 g.) in dry toluene (25 ml) was added dropwise during 1 hour to a stirred suspension of anhydrous aluminium chloride (29.4 g) in dry toluene (150 ml). After stirring a further 20 minutes, the mixture was poured into iced water (1 l) and the organic layer was separated, washed with water, dried over magnesium sulphate, filtered and evaporated. The residue was distilled under reduced pressure and the fraction b.p. 79-80°/0.03 mm was collected. On standing the product solidified and the solid had m.p. 32°-34°.
