Reaktionsschritte

A suspension of pyridinium chlorochromate (8.28 g, 38.4 mmol) and dry celite (5.00 g) in dry dichloromethane was stirred at room temperature for 15 min. 2-Iodobenzyl alcohol (3.03 g, 12.9 mmol) in dry dichloromethane (50 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 solid which was dissolved in dichloromethane and passed through a short silica column, eluting with dichloromethane. The solution was concentrated to give 2-iodobenzaldehyde (19) as a pale yellow oil (2.87 g, 95%).
