PROCEDURE
实验过程
To a solution of 300 mg of ethynyl-phosphonic acid diethyl ester, 494 mg of 1-iodo-2-nitrobenzene and 0.28 ml of di-isopropylamine in 15 ml THF are sequentially added 43 mg of bis-(triphenylphosphin)-palladium(II)-dichloride and 12 mg of copper(I)iodide and the mixture obtained is refluxed for approximately 2 hours. Following an acidic work-up (1N aqueous HCl and EtOAc) and subsequent column chromatography (2-nitro-phenylethynyl)-phosphonic acid diethyl ester is obtained in the form of a slightly brownish oil.
