Versuchsvorschrift

To a solution of (1-allylcyclohexyl)benzene (210 mg, 1.048 mmol) in THF (5 mL) were added a solution of sodium periodate (538 mg, 2.52 mmol) in water (5.00 mL) and 0.105 ml of 2.5% OsO4 in t-BuOH. The mixture was stirred at room temperature for 18 hrs. The mixture was extracted with EtOAc and washed with brine. The combined aqueous layers were back extracted with EtOAc and combined. The resulting material was dried over Na2SO4 and evaporated to give an oily residue. 1H NMR (400 MHz, CDCl3) δ ppm 9.36 (2 H, t, J=3.08 Hz), 7.18-7.42 (5 H, m), 2.58 (2 H, d, J=3.30 Hz), 1.34-1.81 (10 H, m).
