Versuchsvorschrift
94 g (1 mol) of ethylphosphonous acid (produced as in Example 1) and 67 g (1 mol) of methacrylonitrile are introduced into a four-neck round-bottom flask equipped with stirrer, reflux condenser, thermometer and nitrogen inlet and heated. At about 100° C., 98.4 g of a 5% strength solution of AIBN in ethanol are added dropwise over 1 h. Thereafter, the solvent was distilled off in vacuo to leave 137 g of ethyl(2-cyano-2-methylethyl)phosphinic acid.
