反応手順
To a solution of 3-bromobenzaldehyde (30.3 g) and 1-undecyne (29.5 g) in triethylamine (120 ml) was added bis(triphenylphosphine)palladium(II) chloride (1.9 g) followed by copper(I) iodide (0.25 g). The mixture was stirred in the dark at 55° C. for 6 hrs, under nitrogen. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate and filtered. The filtrate was washed with water and saturated sodium chloride solution, dried over anhydrous magnesium sulfate, filtered, and the filtrate was concentrated to yield 45.8 g of 3-(1-undecynyl)benzaldehyde, as an oil.
