Versuchsvorschrift

108 g (0.5 mol) of 6H-dibenz-[c,e][1,2]-oxaphosphorin-6-one are heated to 165° C. with stirring and under an inert-gas atmosphere, and 26.5 g (0.5 mol) of acrylonitrile are added dropwise over 4 hours. The mixture is stirred further at this temperature for 1 hour and then cooled, giving 134 g of a resinous composition. Digestion with a little acetonitrile produces 130 g of 6-(2-cyanoethyl)-(6H)-dibenz[c,e][1,2]-oxaphosphorin 6-oxide, which, after recrystallization from a little acetonitrile, has a melting point of 120-123° C. The yield is 97% of theory.
