实验步骤: 0.96 g (0.02 mol) of sodium hydride was added to 40 ml of dry tetrahydrofuran, and to this solution was added dropwise under reflux a mixed solution of 1.34 g (6 mmol) of ethyl diethylphosphonoacetate and 11 g (0.03 mol) of 1,8-diiodooctane, and the solution was refluxed under heating for 4 hours. After distilling off tetrahydrofuran, the residue was cooled to room temperature, added with 1N hydrochloric acid until the litmus paper came to show acidity of the solution and then extracted three times with 50 ml of ether. After drying the extract over anhydrous sodium sulfate, ether was distilled off and the obtained oily residue was refined by passing through a basic alumina(activity II)-packed column using benzene-ethyl acetate (2:1) as eluent to obtain 1.76 g of 2,2-bis(8-iodooctyl)-diethylphosphonoacetic acid ethyl ester, ##STR35## (yield: 42%). to this solution was added dropwise the solution was refluxed under heating for 4 hours After distilling off tetrahydrofuran added with 1N hydrochloric acid until the litmus paper extracted three times with 50 ml of ether After drying the extract over anhydrous sodium sulfate, ether was distilled off
