Versuchsvorschrift
To a mixture of 0.1 mol of bis(2-cyanoethyl)phosphine oxide and 0.1 mol of acetone was added 1.0 gram of either triethyl amine or pentamethyl guanidine. The mixture was heated for 2 hours at steam bath temperatures. The resulting solid was filtered and recrystallized from acetone to give an 88% yield of product, m.p. 124°-125° C.
