Triphenylphosphine → (1-Methyl-(E)-2-pentenyl)triphenylphosphonium bromide

Participants

Reaction Steps

The compound was prepared from triphenylphosphine and 2-bromo-(E)-3-hexene, a compound which was reported previously (Bianchini and Guillemonat, 1968). Triphenylphosphine (1.6 g, 0.0061 mole) and 2-bromo-(E)-3-hexene (1.0 g, 0.0061 mole) were added to 10 ml dry acetonitrile and refluxed for 6 hr. The solvent was removed by rotary evaporation. The thick, sticky liquid product was stirred with dry ether 4 times, with the ether being decanted. After removing further traces of ether by rotary evaporation, the product was placed in a vacuum desiccator for 6 hr, where the product became a friable white solid (1.6 g, 61%).
