Reaction Steps

40.4 g (0.2 mol) of 6,7,8,9-tetrahydro-2-dibenzofuranmethanol are dissolved in 800 ml of toluene and 176 g (2 mols) of manganese dioxide are added. The dark suspension is stirred at room temperature for 72 hours and then filtered over diatomaceous earth and the resulting filtrate is evaporated to dryness under a waterpump vacuum. 6,7,8,9-Tetrahydro-2-dibenzofurancarboxaldehyde is thus obtained as a dark yellow oily product which, according to the thin layer chromatogram (toluene/ethyl acetate 1:1) is a single compound and can be used for further reactions without additional purification.
