実験手順
20 g (0.135 mol) of ethyl allyl(P-methyl)phosphinate are dissolved in 570 ml of ethyl acetate, 49.7 g (0.6 mol) of sodium bicarbonate in 115 ml of water are added and, while stirring vigorously, a solution of 40.6 g (0.2 mol) of dibromoformaldoxime in 115 ml of ethyl acetate is slowly added dropwise. The product is isolated in the form of an oil, 15 g from the ethyl acetate phase, and a further 19 g from the aqueous phase by extraction with dichloromethane at pH 2.
後処理
- extractiona further 19 g from the aqueous phase by extraction with dichloromethane at pH 2
