Reaction of tetrakis(hydroxymethyl)phosphonium iodide (7.05 g, 0.025 mol) with 1,3-dimethylurea (8.81 g, 0.1 mol) in toluene (25 ml), following Example 1, gave 13.65 g (97.1%) of tetrakis(1,3-dimethylureidomethyl)phosphonium iodide (I, R=R'=CH3, R"=H, X=I) as a white, crystalline solid, mp 194° C. dec after two recrystallizations from ethanol (10 ml/g). The product suffered no weight loss when dried under vacuum for 2 hr at 100° C.
