实验过程

40.3 mmol of benzyl 3-diethylphosphonopropionate (12.1 g) are dissolved in 100 ml of ethanol, and 2 g of catalyst (5% Pd/C) are added. After stirring under an H2 atmosphere for 4 h, the active carbon is filtered off, and the solvent is distilled out. The product results as a colourless oil which slowly solidifies to a colourless solid at room temperature. The product is slightly contaminated with ethyl 3-diethylphosphono-propionate which, where appropriate, can be transferred into the organic phase by shaking several times with water and hexane, and be removed.
