Reaction between ethylenediamine and aryl phosphorodichloridates yields aryl hydrogen N-(2-aminoethyl)-phosphoramidates and not cyclic phosphorodiamidates as reported earlier. I.r. spectroscopy distinguishes between such acids and true cyclic phosphorodiamidates made from trimethylenediamine. 1,2-, 1,3-, and 1,4-Diaminoalkanes cyclise with phenyl phosphorodichloridothionate. o-Phenylenediamine behaves
乙二胺与芳基二氯膦酸酯之间的反应产生芳基氢N-(2-氨基乙基)-磷酰胺基酯,而不是环状的二氨基氨基磷酸酯。红外光谱法将这种酸与由三亚甲基二胺制得的真正的环状二氨基磷酸二酯区分开来。1,2-,1,3-和1,4-二氨基链烷烃与苯基二氯硫代磷酸酯环化。邻苯二胺的行为类似于乙二胺。
