反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 12 g (50 mmol) of hexadecenal and 15.2 g (50 mmol) of formylmethylenetriphenylphosphorane in 250 ml of anhydrous toluene are boiled under reflux for 8 hours. The mixture is evaporated to dryness. The residue is extracted five times with 100 ml of ether. The extract is evaporated to dryness and chromatographed on silica gel using toluene. Yield: 8.2 g (62%). Melting point: 35° C.; RF =0.8, toluene/ethyl acetate 8:2. under reflux for 8 hours The mixture is evaporated to dryness The residue is extracted five times with 100 ml of ether The extract is evaporated to dryness chromatographed on silica gel
