Procedure

A suspension of iodine (13.0 g, 51 mmol) and toluol (100 mL) was heated with reflux for 20 min. The solution formed was cooled to room temperature and added in drops to a solution of triphenylphosphine (14.0 g, 53 mmol) in anhydrous diethyl ether (100 mL). The separated yellow precipitate was filtered off and washed with diethyl ether.
