1,1,1-trifluoro-2-phenylpropan-2-ol

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

Procedure: 1,1,1-Trifluoro-2-phenylpropan-2-ol was prepared from benzene and 1,1,1-trifluoroacetone by an AlCl3 -catalyzed Friedel-Crafts reaction.

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

Procedure: 0.9 g (30 mmol) of sodium hydride (80% strength dispersion in mineral oil) was added to 5 g (26 mmol) of 1,1,1-trifluoro-2-phenylpropan-2-ol in 125 ml of diethyl ether at room temperature. The mixture was stirred for about 1 hour, and 4.75 g (25 mmol) of toluene-4-sulfonyl chloride were then added in portions. Stirring was carried out for 60 hours at room temperature, after which the undissolved constituents were filtered off and the solution was then cooled. 4.3 g of 1,1,1-trifluoro-2-phenyl-2-(toluene-4-sulfonyloxy)-propane were obtained (colorless crystals, m.p.: 102° C. [recrystallized from diethyl ether]). After the mother liquor had been evaporated down, a further 1.6 g of the desired compound could be isolated. Stirring was carried out for 60 hours at room temperature after which the undissolved constituents were filtered off the solution was then cooled
