Diphenylacetic Acid → beta-Phenylphenethyl alcohol

Participants

Reaction Steps

To a rapidly stirring solution of 8.5 g (40 mmol) diphenyl acetic acid in 100 mL dry THF, at room temperature, was added 3.04 g (80 mmol) of LAH. The suspension was stirred at room temperature for 1 hour and then cooled to 0 degrees C. The excess LAH was decomposed by slow addition of 10% NaOH (200 mL aqueous solution). The product was extracted with AcOEt, dried over MgSO4 and concentrated under vacuum to yield 7.1 g (90%) of 2,2-diphenyl ethanol (12).
