Versuchsvorschrift
To 34.1 g of isopropyl 2-cyanoethyl(ethyl)phosphinate in 500 ml of isopropanol are added 60 ml of liquid ammonia and 6.8 g of Raney-Nickel. The mixture is heated to 80° and treated with hydrogen at 100 bar. After 11/2 hours hydrogen-uptake stops. The reaction mixture is filtered and the filtrate distilled to give isopropyl 3-aminopropyl(ethyl)phosphinate as a colorless oil, b.p. 75°/13 Pa.
