摘要: 本文报道了21个0,0一二烷基膦酸酯类化合物的1H、13C和31P NMR参数。研究和讨论了不等价的二烷基1H、13C化学位移和磷碳偶合常数与立体化学的关系。测定了(CH3CH2O)2P(O)CH(CH2NO2)(p-OCH3C6H4)的13C自旋一晶格弛豫时间T1,二乙基13C T1间的差别,说明在类似化合物中,含有化学位移各向异性对弛豫的贡献。

Abstract: 1H, 13C and 31P NMR data are reported for 21 0,0-dialkyl phosphonates. Stereochemical dependence of 1H, 13C chemical shifts in unequal dialkyl groups and 31P 13C spin-spin coupling constants were studied and discussed.13C spin-lattice relaxation times, T1, for (CH3CH20)2P(0)CH(CH2NO2) (p-OCH3C6H4) were measured. There are differences between 13C spin-lattice relaxation in two ethyl groups because the chemical shift anisotropy made contributions to relaxation.
