To a solution of 4-prop-2-ynyl-benzaldehyde (10 mmol) in THF (30 ml), amidosurfulic acid (16 mmol) and water (15 ml) solution of sodium chlorite (30 mmol) are added. The reaction mixture is stirred at room temperature for 2 h. Water is added and then aqueous layer is extracted with two 50 ml portions of CH2Cl2. The combined extracts are washed with brine, dried over sodium sulfate and concentrated under vacuum to give crude product which is purified by silica gel column chromatography. Yield: 62%. Rf=0.44 (n-hexane:AcOEt=7:3)
