Versuchsvorschrift

86.7 parts of triphenylphosphine was dissolved in 200 parts of xylene and 40.0 parts of allyl bromide was added thereto. The mixture was gradually heated and allowed to react at 134° C. for 3 hr. After the mixture was cooled to 30° C., the resulting colorless crystals were collected by filtration and washed with toluene to obtain 122.7 parts of allyltriphenylphosphonium bromide (compound No. 16).
