1-phenyl-2-trimethylsilylethanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A 1.0M solution (75 ml) of trimethylsilylmethyl magnesium chloride in diethyl ether was diluted with dry diethyl ether (50 ml). After the interior of an reaction vessel was replaced by nitrogen, a solution (50 ml) of benzaldehyde (5.3 g) in dry diethyl ether was slowly added dropwise to the solution in the reaction vessel while stirring. The reaction mixture was stirred at 40° C. for 2 hours under nitrogen atmosphere and cooled in an ice bath. A 25% aqueous solution (100 ml) of ammonium chloride was added dropwise thereto, the mixture was extracted with diethyl ether, washed with water and dried over sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 1-trimethylsilyl-2-hydroxy-2-phenylethane (13.1 g) as pale yellow oily material. After the interior of an reaction vessel was replaced by nitrogen The reaction mixture was stirred at 40° C. for 2 hours under nitrogen atmosphere cooled in an ice bath the mixture was extracted with diethyl ether washed with water dried over sodium sulfate After filtration the filtrate was concentrated under reduced pressure

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To benzaldehyde (2.17 g, 20.4 mmol) in 20 mL of ether, 1 M (trimethylsilyl)methyl magnesium chloride solution in ether (28.6 mL) was added at 0° C. After two hours of stirring at 0° C., a saturated NH4Cl solution was added and the mixture was extracted with ether (3×). The combined organic extract was dried (Na2SO4), filtered, and concentrated to give the title product (4.12 g). the mixture was extracted with ether (3×) The combined organic extract was dried (Na2SO4) filtered concentrated
