実験手順
To a suspension of 10.5 g (0.437 mole) of mineral oil free sodium hydride in 1.2 liters of tetrahydrofuran was added dropwise 58.4 g (0.328 mole) of diethylcyanomethyl phosphonate. After the hyrogen evolution had ceased ca 60 min, 69.4 g (0.3 mole) of 2-benzyl-4-chlorobenzaldehyde, in 75 ml of tetrahydrofuran was added dropwise. The mixture was stirred overnight at room temperature. The tetrahydrofuran solution was decanted, and concentrated at room temperature. The residue was partitioned between 2 liters of water and 1.5 liters of ether. The ether solution was separated, washed with water, and dried with sodium sulfate. The ether was removed at reduced pressure to give a yellow oil which was used without further purification.
