149 g (1 mol) of butyl ethyiphosphonite (produced as in Example 2) and 67 g (1.2 mol) of 2-propenal in 217 g of toluene are heated to about 100° C. While stirring, 124 g of a 10% strength solution of WakoV65 in toluene are added by metered addition. The solvent is distilled off in vacuo to leave 171 g (78% of theory) of butyl ethyl(2-formylethyl)phosphinate.
