本文报道了标题类化合物中十个化合物的~1H和~(31)P NMR的研究结果.其中分别运用了2DJ分解谱以及异核COSY谱等多种技术,解析了它们的~1H和~(31)P图谱,从而证实了合成反应的区域选择性和立体选择性.文章中,讨论了因手性中心或其它因素而表现出的不等性;讨论了影响δ_p和J_(PH)数值的各种因素:还报道了比较少见的~(31)P-~(31)P之间的远程偶合.其中,顺式产物的~4J_(pp)数值(约9 Hz)大于反式产物的~4J_(pp)(约7 Hz).
In this paper, the results of ~ 1H and ~ (31) P NMR studies of ten compounds in the title compounds were reported. The 2DJ decomposition and the heteronuclear COZY spectra were used respectively to analyze their ~ 1H and ~ (31) 31) P spectra, confirming the regioselectivity and stereoselectivity of the synthetic reactions.In this paper, we discuss the disparities due to chiral centers or other factors; the effects of δ_p and J_ (PH) values Various factors: It is also reported that the relatively rare ~ (31) P ~ (31) P long-range coupling between them, in which ~ 4J_ (pp) values of cis products (~ 9 Hz) 4J_ (pp) (about 7 Hz).
