Reaction Conditions

Reaction Steps

A mixture of 5-bromo-2-methyl-2-pentene (489.2 mg, 3 mmole) and triphenylphosphine (787 mg, 3 mmole) in 6 ml of acetonitrile was stirred at 95° C. (oil bath temperature) under nitrogen for 20 hours. The solvent was evaporated by a stream of nitrogen. The residue was dried in vacuo at room temperature to give a foam. This was rinsed with ethyl ether to give a white solid which was filtered, washed with ethyl ether and dried in vacuo at 100° C. for 4 hours to afford 905 mg of (4-methyl-3-pentenyl)triphenylphosphonium bromide.
