Versuchsvorschrift

A mixture of 89.0 g. (0.40 mole) of iodo-4-methyl-3,5-hexadiene, 150 g. (0.40 mole) of triphenylphosphine and 350 ml. of benzene was stirred and refluxed for 8 hours. The solvent was removed in vacuo. After addition of about 1 l. of ether the oily mixture was left for one day at 0°. The crystallized salt was suction filtered, finely grinded and washed with ether, then dried for 4 hours at 80°/0.01 Torr. Obtained: 140 g. of phosphonium iodide, m.p. 124°-128°.
