Triphenylphosphonium hydrobromide → Triphenyl[2-(4'-trifluoromethylbiphenyl-4-ylmethoxy)benzyl]phosphonium bromide

Participants

Reaction Steps

A solution of 11.7 g (32.65 mmol) of [2-(4′-trifluoromethylbiphenyl-4-ylmethoxy)phenyl]methanol in 100 ml of acetonitrile is mixed with 10.64 g (31.02 mmol) of triphenylphosphonium hydrobromide and heated under reflux for 3 hours. The reaction solution is then evaporated to dryness, and the resulting oil is taken up and triturated in diethyl ether. The product crystallizes as a white solid. After filtration, the solid is dried in a drying oven at 50° C. overnight. 20.5 g (30 mmol, 92% yield) of crystalline product are obtained.
