Triphenylphosphine → HCID 18383984, compound

Participants

Reaction Steps

Under an argon atmosphere, copper iodide (190 mg, 1.0 mmol), 1-octyne (0.55 mL, 5.0 mmol) and 3-iodo-4-methoxymethoxybenzaldehyde (291 mg, 1.0 mmol) were added to a solution (2 mL) of palladium (II) diacetate (11 mg, 0.05 mmol) and triphenylphosphine (52 mg, 0.20 mmol) in methylene chloride, followed by stirring at room temperature for 2 hours. Next, the reaction solution was filtered through celite, and the solvent contained in the filtrate was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluted with ethyl acetate/hexane=1/10) to give 3-(1-octyn-1-yl)-4-methoxymethoxybenzaldehyde (124 mg, yield 45%).
