3,3,3-trifluoro-2-hydroxy-2-phenylpropanenitrile

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1-Cyano-1-phenyl-2,2,2-trifluoroethanol was prepared from α,α,α-trifluoroacetophenone by a cyanohydrin reaction with potassium cyanide.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 5.2 g (25 mmol) of 1-cyano-2,2,2-trifluoro-1-phenyl-ethanol were dissolved in 50 ml of DMF, and 0.9 g (30 mmol) of sodium hydride (80% strength dispersion in mineral oil) was added. 5.5 g (29 mmol) of toluene-4-sulfonyl chloride were added in portions to the virtually clear solution after about 1 hour. The mixture was stirred for 8 hours, allowed to stand overnight and then poured into water. The oily liquid which separated out solidified on cooling. The solid was filtered off with suction and dried. 6.3 g of 1-cyano-1-phenyl-1-(toluene-4-sulfonyloxy)-2,2,2-trifluoroethane were obtained (colorless crystals, m.p.: 70° C. [from ligroin]). to stand overnight The oily liquid which separated out on cooling The solid was filtered off with suction dried
