this category of phosphorus compounds. The present X-ray structural analysis shows that the H-bond pattern in the studied structures strongly depends on the conformation in the P(O)NHC(O) skeleton and the kind of amide linked to the P atom. The spectroscopic features ( 31 P 1 H}, 1 H and 13 C NMR, IR) of the new compounds have been investigated.
摘要新型磷三酰胺的晶体和堆积结构,在P(O)相对于C(O)的稀疏gauche取向上,分子式为(CCl 2 HC(O)NH)X 2 P(O),X = NC 4 H 8(1),N(C 2 H 5)2(2),N(CH 3)(C 6 H 11)(3)和(CCl 2 HC(O)NH)(Y)P(O), Y = NHCH 2 C(CH 3)2 CH 2 NH(4)已被研究。本文还综述了沉积在CSD中的91种相似结构,旨在对此类磷化合物中的氢键模式进行分类。目前的X射线结构分析表明,所研究结构中的H键模式在很大程度上取决于P(O)NHC(O)骨架中的构象以及与P原子连接的酰胺的种类。研究了新化合物的光谱特征(31 P 1 H},1 H和13 C NMR,IR)。
