diethoxyphosphorylformamide

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: a solution of 54 parts of diethyl carbamoylphosphonate and 36 parts of dimethyl formamide dimethyl acetal was refluxed in 1000 parts of anhydrous tetrahydrofuran for eight hours. The solvent was removed under reduced pressure to give 70 parts of diethyl 1-dimethylaminomethyleneaminocarbonylphosphonate, nD24 = 1.4970. The solvent was removed under reduced pressure
