Benzene-1,3,5-triyltrimethanol (400 mg, 2.38 mmol) was suspended in 8 ml of tBuOH, and IBX (4.00 g, 14.27 mmol, 6 equiv) was added. The mixture was heated to reux and stirred for 5h. The suspension was cooled to rt and the solids were filtered off, and subsequently washed with CH2Cl2. The clear liquid was evaporated to dryness, yielding the tri-aldehyde as white powder (385 mg, 2.38 mmol, quant). 1H NMR (500 MHz, Chloroform-d) 8 10.21 (s, 3H), 8.64 (s, 3H). 130 NMR (126 MHZ, CDCl3) 6 189.78, 137.80, 134.76.
