実験手順: A suspension of pyridinium chlorochromate (2.45 g, 11.4 mmol) and dry celite (˜2.00 g) in dry dichloromethane (20 ml) was stirred at room temperature for 15 min. 3-Iodobenzyl alcohol (11) (1.02 g, 4.35 mmol) in dry dichloromethane (5 ml) was added. The suspension was shielded from light and stirred at room temperature for 2 h after which it was diluted with ether, and filtered through celite. The cloudy brown filtrate was concentrated to a red-brown gummy paste which was re-dissolved in dichloromethane and passed through a short silica column, eluting with dichloromethane. This gave a clear, colourless solution which was concentrated to give 3-iodobenzaldehyde (12) as a white solid (0.953 g, 95%). dry celite (˜2.00 g) in dry dichloromethane (20 ml) stirred at room temperature for 2 h after which it filtered through celite The cloudy brown filtrate was concentrated to a red-brown gummy paste which was re-dissolved in dichloromethane eluting with dichloromethane This gave a clear, colourless solution which was concentrated

実験手順: Acetonitrile addition to 3-iodobenzaldehyde (103) yielded 3-hydroxy-3-(3-iodophenyl)propanenitrile (104) as yellow oil. Yield (2.58 g, 55%): 1H NMR (400 MHz, CDCl3) 7.82 (s, 1H), 7.70 (d, J=8.0 Hz, 1H), 7.38 (d, J=8.0 Hz, 1H), 7.14 (t, J=8.0 Hz, 1H), 5.01 (m, 1H), 2.80 (d, J=6.4, 2H), 2.40 (bs, 1H).
