14 react smoothly with diazomethane to give 2-phosphono-1-vinylaziridines 18. The synthesis of 2-ethoxycarbonyl-3-phosphono-1-vinylaziridines 19 was performed using ethyldiazoacetate (EDA) in the presence of ytterbium(III) tritlate as a catalyst. 2-Phosphono-3-(trimethylsilyl)aziridines 20 were prepared from phosphonoazadienes 14 by treatment with (trimethylsilyl)diazomethane under reflux. 1-Aryl-1-phosphono-2-aza-1
