【摘要】 用³¹P对烷基膦酸二烷基酯,乙酰丙烯磷酸二烷基酯的组成进行了分析,为寻找反应条件和产品纯化方法提供了有益的数据。并对几种腺嘌呤核苷酸磷酸酯及磷酰胺不同的立体异构体进行了测定,平展式较直立式在高场约2ppm处共振。更多还原

【Abstract】 31P NMR spectroscopy was used to identify various alkyl dialkyl phosph-onates and acetoallyl dialkylphosphonates. Quantitative results were also obtained to correlale with conditions of preparation and purity of products.Two steric structures of cyclic adenosine-3’,5’- phosphates identified as well.31P chemical shift of axial and equatorial form differ by 2ppm.更多还原
