Versuchsvorschrift

A solution of triphenylphosphine (Aldrich, 11.7 g) and 3,3,3-trifluoropropyl iodid (Lancaster, 10 g) was vigorously refluxed in xylenes (75 mL) for 2 days. The solid which formed was filtered and washed with xylenes then air dried to yield a white solid (16.6 g). 1H NMR and elemental analysis are consistent with the proposed structure.
