Procedure

A stirred solution of 52.3 g (0.5 mole) of 3-methyl-2-butenyl chloride and 144.1 g (0.55 mole) of triphenylphosphine in 400 ml of toluene was heated at 100° C. for 18 hours. The white solid formed was collected by filtration to give 147.6 g of (3-methyl-2-butenyl)triphenylphosphonium chloride.
