General procedure: In a typical experiment, complex 1 (6.1 mg, 10 tmol) and H[BAr’4].(Et2O)2 (10.1 mg, 10 tmol) were dissolved in THF (2.0 mE) in a 100 mE thick-walled glass vessel equipped with a TEFLON stopcock and a stir bar. The substrate (0.5 mmol) to be hydrogenated was then added. The vessel was degassed by freeze-pump-thaw and then hydrogen (1 or 4 atm) was added. The resulting solution was stirred at the desired temperature (25-60° C.) for the indicated reaction time. At the end of the reaction, the solvent was evaporated and the residue was passed through silica gel in a pipette. The solvent was removed under vacuum and the ‘H NMR spectrum of the crude product mixture was recorded in CDC13. Hydrogenation products were then isolated by column chromatography or preparative thin layer chromatography (“TLC”) using n-hexane/ethyl acetate (3:1, v/v) as an eluent. Isolated products were characterized by ‘H NMR and GCMS, with spectra matching those reported in the literature or authentic samples.

2.4. Typical Procedure for the Reduction of Ketones withZn(BH4)2/2NaCl System in CH3CN General procedure: In a round-bottomed flask (10 mL), equipped with a magneticstirrer bar, a solution of acetophenone (0.121 g, l mmol) was prepared in CH3CN(3 mL). To this solution, Zn(BH4)2/2NaCl (0.210 g,1 mmol) was added. The resulting mixture was stirred at room temperature for 60 min. The reaction was monitored by TLC(eluent; Hexane/EtOAc: 10/1). After completion of the reaction, distilled water (5 mL) was added to the reaction mixture and stirred for 5 min. The mixture was extracted with CH2Cl2 (3 ×8 mL) and dried over anhydrous Na2SO4. Evaporation of the solvent followed column chromatography of the resulting crude material over silica gel (eluent; Hexane/EtOAc: 10/1) afforded crystals of 1-phenylethanol (0.l1 g, 93 percent yield,Table 2, entry 11).

Reactions of ketones and aldehydes with AB in methanol General procedure: A 0.5 mm NMR tube was charged with ketone or aldehyde (0.2 mmol), AB (0.1 mmol), and deuterated methanol. The tube was covered with a plastic cap and inserted into the NMR machine after shaking. The reaction courses were monitored by 1H and 11B NMR every several minutes (depending on the reaction rates). The typical resonances of the starting materials gradually decreased while new signals of the saturated products appeared. After the ketone or aldehyde disappeared completely in the 1H NMR spectrum, 13C NMR spectrum was recorded. For a large scale reaction in normal methanol, the solvent and all volatile compounds (trimethyl borate and ammonia) were removed by high vacuum after the reaction, and the remaining alcohol was pure to the limit of the NMR with nearly 100percent yield.

The reaction mixture was heated at 82 °C for the required reaction time under an atmosphere of nitrogen. Aliquots (0.2 mL) were taken at fixed time and the catalyst removed as precipitate from the reaction mixture by the addition of diethyl ether. The organic layer was neutralized with 1 N HCl, washed with water and dried over anhydrous Na2SO4. The combined organic layer passed through a short path of silica gel and then subjected to GCMS analysis.

General procedure for copper-catalyzed benzylic oxidation (substrate scope) General procedure: A solution of copper(II) trifluoromethanesulfonate (11.1 mg, 0.03 mmol) and ligand 10a (8.4 mg, 0.036 mmol) in dry acetone (5 mL) was stirred at room temperature for 1 h. Phenylhydrazine (3.9 mg, 0.036 mmol) was added to this dark brown solution, and the solution became purple immediately. After stirring for additional 5 min, the benzylic substrate (3 mmol) and the oxidant tert-butyl benzoate (117 mg, 0.6 mmol) were then introduced successively. The mixture was stirred at 30 &deg;C for a certain time until the reaction was completed (determined by the disappearance of perester by TLC). After the solvent was evaporated in vacuum with a rotary evaporator, the residue was purified by silica gel chromatography using petrol ether/EtOAc as eluent to give the desired products.
