利用~(13)C核磁共振可以研究化合物的电子结构,尤其是叶立德的电子结构和电荷分布,但膦叶立德~(13)C核磁共振的研究报道较少。Gray报道六个膦叶立德的~(13)C核磁共振研究,测定了化学位移和偶合常数,叶立德的~1J_(CP)在30％范围内变动。~1J_(CP)可以反映叶立德键的s-特性,随着~1J_(CP)的增加,s-特性亦增加。
The electronic structures of the compounds, especially the electron structures and charge distributions of Yelv Teh, can be studied by 13 C nuclear magnetic resonance. Gray reported the ~ (13) C nuclear magnetic resonance studies of six phosphinilides and determined the chemical shifts and coupling constants. The ~ 1 J_ (CP) of Ylidod varied within 30%. ~ 1J_ (CP) can reflect the s-characteristics of the Yeltshehr bond. With the increase of ~ 1J_ (CP), the s-properties also increase.
