Procedure
10.4 parts of cinnamyltriphenylphosphonium chloride prepared in the above Synthetic Example 2 was dissolved in 580 parts of water and a solution of 2.7 parts of sodium tetrafluoroborate in 9 parts of water was slowly added dropwise thereto. After 6 hr stirring, the resulting colorless crystals were collected by filtration, washed with 300 parts of water, and dried to obtain 10.1 parts of cinnamyltriphenylphosphonium tetrafluoroborate (compound No. 5).
