N-(Substituted aryl/cyclohexyl)-N'-[5-bromo-5-nitro-2-oxido-1,3,2-dioxaphosphorinane-2-yl]ureas RR'P(O)NHC(O)NHR' (5) were synthesized by the reactions of 2-bromo-2-nitro-1,3-propanediol (4) with chlorides of aryl/cyclohexyl carbamidophosphoric acids (3) in the presence of triethylamine at room temperature. Their ir, 1H, 13C and 31P nmr spectral data are discussed.
N-(取代的芳基/环己基)-N' -[5-溴-5-硝基-2-氧化-1,3,2-二氧杂膦烷基-2-基]脲RR'P(O)NHC(O)NHR' (5)是在室温下在三乙胺存在下,使2-溴-2-硝基-1,3-丙二醇(4)与芳基/环己基氨基甲酰磷酸(3)的氯化物反应合成的。讨论了他们的ir,1 H,13 C和31 P nmr光谱数据。
