Reaction Steps
A slight excess (5-10%) of gaseous ammonia is introduced into a stirring mixture of 11 parts of diallyl methoxycarbonylphosphonate (from triallyl phosphite and methyl chloroformate) and 200 parts of tetrahydrofuran. The temperature increases from 25° to 28° C. spontaneously. The mixture is then heated to 35° C. and maintained at this temperature for 2 hours. The slightly hazy solution is filtered, and solvent is removed from the filtrate at 50° C. under reduced pressure (15 mm.). The residual solid is recrystallized from benzene, giving 6 parts of white crystalline diallyl carbamoylphosphonate, m.p. 91°-94° C.
