Reaction Steps

A 500 ml five-neck flask equipped with thermometer, reflux condenser, high-performance stirrer and dropping funnel is initially charged with 63.5 g (0.46 mol) of 2-hydroxyethyl ethylphosponite (produced as in Example 4) and 32.2 g (0.46 mol) of 2-methyl-2-propenal. While stirring, 25 ml of sodium ethoxide (30% in ethanol) are added dropwise at such a rate that a reaction temperature of 60° C. becomes established. A slightly yellow-colored liquid is obtained. The crude product thus obtained is distilled in vacuo to obtain 84 g (88% of theory) of 2-hydroxyethyl ethyl(2-methyl-2-formylethyl)phosphinate as colorless liquid.
