Aerobic Oxidation of Benzylic Alcohols The oxidation of 1-phenyl-1-pentanol (1a) is representative (Table 2, entry 1): BMI-PF6 (85 mg, 0.30 mmol), 1-phenyl-1-pentanol (1a, 33 mg, 0.20 mmol), Cs2CO3 (33 mg, 0.10 mmol), and trifluoromethylbenzene (0.10 mL) were placed in a reaction flask with a reflux condenser and a drying tube lined with calcium chloride. The resulting mixture was stirred for 20 h at 105 °C. The reaction mixture was diluted with ethyl acetate and poured into water. The mixture was extracted with ethyl acetate three times.

The combined organic layer was dried over Na2SO4, filtered through a pad of neutral alumina, and concentrated under reduced pressure. Purification by column chromatography on silica gel with hexane/ethyl acetate (10:1, v/v) as an eluent afforded 1-phenyl-1-pentanone (2a, 28 mg, 0.17 mmol) in 86percent yield.

4.6 Oxidation of alcohols under open-air atmosphere General procedure: VOSO4·5H2O (126.5 mg, 0.5 mmol), 4,4α-di-tert-butyl-2,2α-bipyridyl (268.4 mg, 1 mmol), and p-nitrobenzhydrol (229.3 mg, 0.05 mmol) were placed in a 100 mL round-bottomed flask, and then water (50 mL) was added. Next, the mixture was stirred, and then anhydrous MgSO4 (18.06 g, 150 mmol) was slowly added into the mixture (cooling by ice water).

After that, substrate (10 mmol) was added into the mixture at room temperature, and the mixture was stirred at 90 °C for the appropriate time under open-air atmosphere. After the reaction, the mixture was extracted with ethyl acetate and dried over anhydrous MgSO4. The extracts were concentrated in vacuo. Purification of the products was carried out by silica gel column chromatography using hexane and diethyl ether as eluent to afford the analytically pure ketones. In Table 7 (entries 3, 7, and 8), crude products were purified by recrystallization with ethyl acetate in refrigerator, afforded analytically pure ketones. The product was identified by comparison with the commercially available sample using 1H NMR spectroscopy.

Conditions & References 13 : 4.2. General procedure for the direct transformation of tertiary amides into ketones and amines General procedure: Tf2O (1.2 equiv) was added dropwise to a cooled (−78 °C) solution of amide 5 (1.0 equiv) and DTBMP (1.2 equiv) in CH2Cl2 (5 mL). The reaction was allowed warming to 0 °C over 2 h. A solution of Grignard reagent (1.0 equiv) in Et2O was added dropwise to the resultant mixture at −78 °C, and the mixture was stirred at the same temperature for 2 h. The reaction mixture was then quenched with an aqueous solution of 15percent HCl (5 mL). The organic layer was separated and the aqueous phase was extracted with diethyl ether (3×5 mL). The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by flash column chromatography on silica gel to afford the desired ketone 1. To isolate the corresponding amine, the aqueous solution layer was basified with an aqueous solution of 15percent NaOH (6 mL), and extracted with dichloromethane (3×10 mL), the combined organic layers were dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by flash column chromatography on silica gel to afford the desired amine 6.

While carrying out the pseudo-first order kinetic experiments, the volume of the reaction mixture was kept constant in order to keep the concentration of benzoyl chloride 2 constant. The mixture was quickly thermostated by immersing the flask cooling bath at constant temperature on a magnetic stirrer. Aliquots (10-16) were withdrawn from the mixture by syringe under nitrogen atmosphere at 5 or 5 min intervals and were hydrolyzed in a vial containing saturated NH4Cl solution containing 20percent NH3.

The aqueous phase was extracted with ether and the ethereal phase was analyzed by GC. The rate data were collected by measuring the concentration of coupling products 3a and 3b in each sample. Self consistent data could be obtained for two-four half lives. Reproducibility of the rate constants was generally +/-5-10percent which is in the error limit of GC analysis. in tetrahydrofuran, T= 0 °C , Inert atmosphere, Kinetics, Concentration, Temperature Pekel, Oezgen Oemuer; Erdik, Ender; Journal of Organometallic Chemistry; vol. 751; (2014); p. 644 - 653 View in Reaxys

Conditions & References A typical kinetic procedure for reaction of n-BuPhCuZnI 1ab with benzoyl chloride 2 in THF at -15 °C under pseudofirst order conditions in the presence of excess 1ab General procedure: In a flame-dried, two-necked flasks with septum caps and stirring bars, n-BuPhCuZnI 1ab (10 mmol) was prepared using THF solution of ZnCl2 (10 mmol), PhMgBr (10 mmol) in THF, n-BuMgBr(10 mmol) in THF and CuI (10 mmol) at 15 °C as explained above.To the stirred mixture, internal standard nonane (1 mmol) and PhCOCl 2 (1 mmol) was added.

While carrying out the pseudo-first order kinetic experiments, the volume of the reaction mixture was kept constant in order to keep the concentration of benzoyl chloride 2 constant. The mixture was quickly thermostated by immersing the flask cooling bath at constant temperature on a magnetic stirrer. Aliquots (10-16) were withdrawn from the mixture by syringe under nitrogen atmosphere at 5 or 5 min intervals and were hydrolyzed in a vial containing saturated NH4Cl solution containing 20percent NH3.

A dry and argon-flushed flask, equipped with a magnetic stirring bar and a septum, was charged with morpholine (0.18mL, 2.1mmol) and 10mL THF. After cooling to 0°C, DIBALH (2.0mL, 1.0M in hexane, 2.0mmol) was added dropwise and stirred for 3h at same temperature. To a reaction mixture was slowly added ethyl benzoate (0.14g, 1.0mmol) and stirred for 10min. Then, n-BuLi (1.25mL, 1.6M in hexane, 2.0mmol) was added and the mixture was stirred for 10min again. The reaction was stopped by the aqueous 1N HCl (10mL) and extracted with diethyl ether (2×10mL). The combined organic layers were dried over MgSO4, filtered, and concentrated under reduced pressure. Purification of the residue by column chromatography on silica gel yielded 1phenylpentanone (150mg, 92percent).

Alkyl Aryl Ketones 3 and 2-Arylbenzofurans 4; General Procedure General procedure: To a Schlenk tube with a magnetic stirring bar were charged the respective nitrile 1 (0.4 mmol), arylboronic acid 2 (0.8 mmol), Pd(OAc)2 (5 molpercent), bpy (10 molpercent), TFA (10 equiv), THF (2 mL), and H2O (0.4 mL) under N2 atmosphere. The reaction mixture was stirred at 80 °C for 36 h. After cooling to r.t., the mixture was poured into EtOAc (5 mL), which was washed with sat. aq NaHCO3 (2*10 mL) and then brine (1*10 mL). After extracting the aqueous layer with EtOAc (3*10 mL), the combined organic layers were dried (Na2SO4), and evaporated under vacuum. The residue was purified by flash column chromatography (hexane–EtOAc) to afford the desired products 3 or 4. All known compounds afforded analytical data identical to those reported literature previously (see Supporting Information for further details).

The resultant suspension was stirred vigorously while a solution of tBuOOH (2) (5.0-6.0 M in decane, 360 μL, 2.0 mmol) was added dropwise over 1 h. After the addition, the reaction mixture was stirred for 11 h followed by chromatography on silica gel with n-hexanes/EtOAc (10:1) to yield 4-methoxybenzonitrile (9a) as a yellow oil (55.3 mg, 83percent).

Then trifluoroacetic acid (22.5 μL, 0.3 mmol) was added dropwise via syringe under nitrogen and the resulting mixture was stirred for additional 30 mins. Bromohydrins (0.5 mmol) was added to the reaction mixture and then the ice bath was removed. The solution was allowed to stir at room temperature until TLC indicated complete consumption of the starting bromohydrins. The reaction mixture was concentrated in vacuo, and purified by column chromatograph packed with silica gel using petroleum ether/ethyl acetate (50:1 to 10:1) as eluent to afford the pure products.
