Versuchsvorschrift

(1)-2 To a solution of di-tert.-butyl trans-1-propenylphosphonate (12.0 g.) in carbon tetrachloride (120 ml.) were added basic aluminum oxide (24.0 g.), N-bromosuccinimide (10.95 g.) and then dibenzoylperoxide (1.4 g.). The mixture was heated to reflux for an hour and then stirred for 30 minutes under ice-cooling. The resultant mixture was filtered and the filtrate was evaporated to dryness under reduced pressure to give oily di-tert.-butyl 3-bromo-trans-1-propenylphosphonate (17.2 g.).
