Phosphorimidates and related compounds (R1R2R3P:NR4) have been prepared by Staudinger reactions between three-co-ordinate phosphorus nucleophiles and azides. I.r., mass, and n.m.r. spectral studies on the compounds are reported. Low-temperature 1H n.m.r. studies suggest that the rotational barrier around the P:N bond in these compounds is below 8 kcal mol–1. Thermal rearrangements of some methyl phosphorimidates
通过三配位磷亲核试剂和叠氮化物之间的斯托丁格反应制备了亚磷酸酯和相关化合物(R 1 R 2 R 3 P:NR 4)。对该化合物进行了Ir,质量和nmr光谱研究。低温1 H nmr研究表明,这些化合物中P:N键周围的旋转势垒低于8 kcal mol –1。已经观察到一些亚氨基磷酸亚磷酸酯热重排为氨基磷酸酯[ P(OMe):NMe → F P(:O)NMe 2 ]。
