4-(2-hydroxypropan-2-yl)benzaldehyde

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-[4-(Hydroxymethyl)phenyl]propan-2-ol (1.0 g, 6 mmol) was dissolved in the mixture of ethyl acetate (10 mL) and dichloromethane (5 mL). To the solution, MnO2 (2.6 g, 30 mmol) was added, and the mixture was stirred overnight at room temperature. The solid was filtered off and washed with ethyl acetate. The combined organic phases were concentrated to afford the title compound. 1H NMR (400 MHz CDCl3): δ 10.00 (s, 1H), 7.80 (d, 2H), 7.60 (d, 2H), 1.60 (s, 6H). The solid was filtered off washed with ethyl acetate The combined organic phases were concentrated
