Versuchsvorschrift
9.6 parts of allyltriphenylphosphonium bromide prepared in the above Synthetic Example 1 was dissolved in 140 parts of water and a solution of 2.8 parts of sodium tetrafluoroborate in 9 parts of water was slowly added dropwise thereto. After 5 hr stirring, the resulting colorless crystals were collected by filtration, washed with 200 parts of water, and dried to obtain 6.5 parts of allyltriphenylphosphonium tetrafluoroborate (compound No. 1).
