Procedure
A solution of 1 g of 3-aminopropyl(but-3-enyl)phosphinic acid in 25 ml of water is treated with 0.1 g of 5% palladium on charcoal and hydrogenated at room temperature until hydrogen uptake ceases. The catalyst is removed by filtration of the reaction mixture through celite and the filtrate evaporated to dryness, to afford 3-aminopropyl(butyl)phosphinic acid, m.p.231°-234° (dec.) 31 -NMR (D2O): δ+44.6 ppm.
