2-Benzyl-4-chlorobenzyl alcohol → 2-Benzyl-4-chlorobenzaldehyde

Participants

Reaction Steps

To a suspension of 238 g (1.1 mol) of pyridinium chlorochromate and 300 ml of methylene chloride were added 79.3 g (0.34 mol) of 2-benzyl-4-chlorobenzyl alcohol. The mixture was stirred at room temperature for 2 hours. The chromium salts were precipitated by the addition of 2.4 liters of a 1:1 mixture of ether and petroleum ether, and the precipitate was removed by filtration through Celite. The solvent was removed at reduced pressure to give a yellow oil, which was used without further purification.
