Reaction Conditions:
with potassium formate;Ru(OTf)[(S,S)-iso-BuSO2dpen](p-cymene) in methanol at 50; for 24 h;Inert atmosphere;
Steps:
23
Working Example 23; A ruthenium complex Ru(OTf)[(S,S)-iso-BuSO2dpen] (p-cymene) (1.4 mg, 0.002 mmol), potassium formate (1.0 g, 12 mmol), and 3',5'-bis(trifluoromethyl)acetophenone (2.56 g, 10 mmol, substrate/catalyst ratio=5000) were set in a 20 mL glass Schlenk-type reaction tube under an argon atmosphere. Methanol (6 mL) was added thereto and stirred at 50° C. for 24 hours to give (S)-1-[3',5'-bis(trifluoromethyl)phenyl]ethanol at 100% yield and 87.7% ee optical purity.
