(3-Benzyloxy-4-iodophenyl)methanol → 3-(Benzyloxy)-4-iodobenzaldehyde

Participants

Reaction Steps

A solution of 125 g (370 mmol) of 3-benzyloxy-4-iodobenzyl alcohol and 160 g (1.84 mol) of manganese dioxide in 750 ml of dichloromethane is stirred at room temperature for 18 hours. Since the reaction is not complete, a further 160 g (1.84 mol) of manganese dioxide are added and the medium is stirred for 6 hours. The reaction medium is filtered through Celite and the filtrate is then concentrated under vacuum. 114 g (92%) of 3-benzyloxy-4-iodobenzaldehyde are obtained in the form of a yellow oil.
