90% With 2,2,6,6-Tetramethyl-1-piperidinyloxy free radical; copper diacetate; In water; acetonitrile; at 20℃; for 6h;Green chemistry; General procedure: A mixture of alcohol (5.0 mmol), Cu(OAc)2 (9.1 mg, 0.05 mmol), and TEMPO (7.8 mg, 0.05 mmol) in CH3CN/H2O (5/10 mL) was stirred at room temperature for specified time. After completion of the reaction (monitored by TLC, eluents: petroleum ether/ethyl acetate = 4/1), dichloromethane (10 mL) was added to the resulting mixture. The dichloromethane phase was separated, and the aqueous phase was further extracted with dichloromethane (10 mL × 2). The combined organic layers were dried over anhydrous sodium sulfate and concentrated to give a residue, which was purified by column chromatography (eluents: petroleum ether/ethyl acetate = 10/1) to provide the desired product.

YieldReaction ConditionsOperation in experiment
82.5% With hydrogen;aluminum nickel; In toluene; Example 5 (not according to the invention) 37 g of 3,5-bis(trifluoromethyl)benzaldehyde and 4 g of Raney nickel together with 150 ml of toluene were placed in a reaction vessel at room temperature. The vessel was pressurized with 30 bar of hydrogen gas and the mixture was hydrogenated at 50 C. for 7.5 hours while stirring. The mixture was subsequently cooled to room temperature, depressurized and the catalyst was filtered off. The filtrate was evaporated and the crude product obtained in this way was distilled at 17 mbar. 3,5-bis(trifluoromethyl)benzyl alcohol having a boiling point of 97 C. was obtained in a yield of 31.5 g and a purity of 97.7%. This corresponds to a yield of 82.5% of theory.
