5,10-二氢磷杂吖嗪衍生物结构的核磁共振波谱表征

STRUCTURE ELUCIDATION AND NMR CHARACTERIZATION OF 5,10-DIHYDROPHENOPHOSPHAZINE DERIVATIVES

用~1H,^(13)C NMR及多种二维核磁共振谱进一步确定了本系列化合物5,10-二氢磷杂吖嗪衍生物的结构,完成了~1H和^(12)C NMR谱峰的全归属,探讨了影响偶合常数大小的因素。

The structures of thirteen 5,10-dihydrophenophosphazine derivatives were elucidated by ~1H, ^(13)C and two-dimensional NMR. The ~1H and ^(13)C chemical shifts were assigned, and the coupling constants between ^(19)P and ~1H/^(13)C were determined accurately. The factors affecting coupling constants were also investigated.
