What is R(+)-1-(PENTAFLUOROPHENYL)ETHANOL?

Purification Methods

Recrystallise the ethanol from n-pentane at -40o and sublime it at 25o/0.3mm (use ice-cooled cold finger). It has also been purified by column chromatography through Kieselgel 60 (0.063-0.2mm mesh, Merck) and eluted with EtOAc/n-hexane (1:5), then recrystallised from n-pentane and sublimed in a vacuum. It has RF on Kieselgel 60 F254 TLC foil and eluting with EtOAc/n-hexane (1:5). [Meese Justus Liebigs Ann Chem 2004 1986.]
