実験手順

A 200-ml four-necked flask sufficiently purged with nitrogen was equipped with a stirrer, a thermometer and a reflux condenser. 5.5 g (40 mmol) of trichlorophosphine and 40.0 ml of tetrahydrofuran were weighed in the flask. A cyclopentylmagnesium chloride solution was added dropwise to the flask at an internal temperature of 10-20° C. over a period of 3 hours, wherein the solution had been previously prepared from 13.8 g (132 mmol) of cyclopentyl chloride and 3.2 g (132 mmol) of metallic magnesium in 49 g of tetrahydrofuran. The mixture was stirred at 20-30° C. for 2 hours. Gas chromatography analysis confirmed the disappearance of trichlorophosphine. After the completion of the reaction, 61 ml of toluene was added, and 11.8 g (6 mmol) of 5% sulfuric acid was added dropwise to dissolve the magnesium salt, followed by separation. The organic phase was washed with 11.8 ml of water, and a solution of tricyclopentylphosphine was obtained.
