With iodosylbenzene; In acetonitrile; at 60℃; for 2h; | General procedure: Oxidation of alcohols was typically carried out as follows: a suspension with 5 mg of the synthesized catalyst in acetonitrile (2 mL) was magnetically stirred, and the substrate namely alcohols (0.1 mmol) and PhIO (2.5 equiv.) was then added. The resulting mixture was kept at 60 C with magnetical stirring for a set time. The selectivity and conversion were determined by GC analysis. |

64% | With sodium tetrahydroborate; In methanol; at 0℃; for 1h;Inert atmosphere; | Under nitrogen atmosphere, at 0C, to a stirred solution of NaBH4 (0.56 g, 14.7 mmol) in dry MeOH (10 mL), 3-phenylbenzaldehyde (0.67 g, 3.68 mmol) in dry MeOH (7 mL) was added via a cannula. After lh, the crude was quenched with water and concentrated to dryness. The resulting oil was dissolved in AcOEt and extracted with water. The organic fraction was dried over Na2S04, filtered and subsequently purified by column chromatography using a Teledyne ISCO apparatus, eluting with Cy/TBME (from 100:0 to 50:50) to afford the title compound (0.432 g, 64%) as a pure product. 1HNMR (CDC13): delta 1.62-1.78 (m, 1H), 4.80 (d, J= 6.0, 1H), 7.33-7.75 (m, 9H). 66421 |

Preparation of (3-phenylphenyl)-methanol Under nitrogen atmosphere, at 0 C., to a stirred solution of NaBH4 (0.56 g, 14.7 mmol) in dry MeOH (10 mL), 3-phenylbenzaldehyde (0.67 g, 3.68 mmol) in dry MeOH (7 mL) was added via a cannula. After 1 h, the crude was quenched with water and concentrated to dryness. The resulting oil was dissolved in AcOEt and extracted with water. The organic fraction was dried over Na2SO4, filtered and subsequently purified by column chromatography using a Teledyne ISCO apparatus, eluting with Cy/TBME (from 100:0 to 50:50) to afford the title compound (0.432 g, 64%) as a pure product. 1H NMR (CDCl3): delta 1.62-1.78 (m, 1H), 4.80 (d, J=6.0, 1H), 7.33-7.75 (m, 9H). |
With sodium borohydrid; ammonium chloride; In tetrahydrofuran; methanol; | (2) To a solution of 5.47 g (30 mmol) of 3-phenylbenzaldehyde in 50 ml of dry methanol and 50 ml of dry tetrahydrofuran was added 1.34 g (32 mmol) of sodium borohydride portionwise with ice-cooling, and further the mixture was stirred for 1 hour with ice-cooling. The reaction mixture was added to 400 ml of an about 5% aqueous solution of ammonium chloride, and the mixture was extracted with tert-butyl methyl ether. The organic layer was dried and concentrated to obtain 5.57 g (30 mmol) of 3-phenylbenzylalcohol. |
With 2,4,6-trimethyl-pyridine; hydrogen; In isopropyl alcohol; at 100℃; under 4500.45 Torr; for 24h; | General procedure: A typical procedure for the hydrogenation of aldehydesis as follows: aldehyde (1 mmol), Au catalyst, and 2 mL ofsolvent were placed in a modified Fischer-Porter 100 mLglass reactor. The reactor was purged five times with H2,leaving the vessel at the desired pressure. The resultingmixture was vigorously stirred, and the temperature wasmaintained with an oil bath. After the desired time, thecatalyst was removed by centrifugation and the productswere analyzed by GC with an internal standard to determinethe conversion and selectivity |

53% | General procedure: Trans-2-phenylcyclopropylamine hydrochloride (1.0 eq.), acetic acid (1.0eq.) and the appropriate aldehyde (0.9 eq.) were dissolved in around bottom flask in 10 mL dry DCE. The reaction mixture was stirred gently at room temperature for 2 h before sodium triacetoxyborohydride (3.0 eq.) was added in small portions to the reaction vessel. The reaction was monitored by TLC and quenched using 10 mL of an aqueous (5%) NaHCO3 solution. The organic layer was separated and the aqueous layer extracted three times with10 mL of DCE. All organic layers were combined, dried over anhydrous Na2SO4, concentrated in vacuo and purified using flash chromatography (silica gel; cyclohexane/ethyl acetate) to give the desired compound. |
