A mixture of pentafluorobenzyl fluoride (0.37 g), N-bromosuccinimide (0.36 g) and dry carbon tetrachloride (30 ml) was heated under reflux and irradiated with ultra violet light for a period of 4 hr. The reaction mixture was cooled, the insoluble material was removed by filtration and the solvent was removed by distillation under reduced pressure to give α-bromopentafluorobenzyl fluoride. The product was characterised by p.m.r. spectroscopy. Chemical shift δppm (solvent CDCl3): 7.63 (d, J=48 Hz).
