??

(S)?-?(+)?-?α-?(Trifluoromethyl)?benzyl Alcohol is used in the synthesis of metal-organic framework compounds which may have mesoporous properties.

Purification Methods

Purify the chiral alcohols by fractional distillation preferably in a vacuum. [Morrison & Ridgeway Tetrahedron Lett 573 1969, NMR: Pirkle & Beare J Am Chem Soc 90 6250 1968.] The racemate [340-05-6] has b 52-54o/2mm,57-59o/2mm, 64-65o/5mm, d 4 20 1.293, n D 20 1.457, and the 2-carbobenzoyl derivative has m 137-138o [Mosher et al. J Am Chem Soc 78 4374 1956]. [Beilstein 6 IV 3043.]
