【摘要】 合成了11个新的硫代磷酰胺烷基炔丙基酯,采用IR和NMR对目标化合物进行了表征。¹H NMR清楚地显示与磷原子相连的炔丙氧基同时存在P—O旋转受阻和自由旋转,进一步由¹³C NMR证实。更多还原

【Abstract】 Eleven new compounds of O-alkyl-O-propargyl-phosphoramidoth|onates were synthesized, which were characterized by IR and NMR. The ¹H NMR spectra showed the simultaneous exstences of the free rotation and resticted rotation aboat P-O bond in the group HC≡C-CH₂O-P in each molecule, as was confirmed by ¹³C NMR.更多还原
