実験手順

25.0 g (0.139 mol) of 9,10-dihydrophenanthrene, 6.30 g (27.6 mmol) of periodic acid and 17.0 g (67.0 mmol) of iodine are heated at 70° C. for 1 h in a solution of 4 ml of conc. sulfuric acid and 28 ml of water in 140 ml of glacial acetic acid. The solution is subsequently added to ice-water and extracted three times with ethyl acetate. The combined org. phases are washed with sat. sodium hydrogencarbonate soln. and dried over sodium sulfate. The solvent is removed in vacuo, and the residue is distilled in a bulb tube at 170° C. and 0.3 mbar, giving 2-iodo-9,10-dihydrophenanthrene as yellow oil.
