We present the synthesis and characterization of seven new phosphoric triamides followed by analysis of hydrogen bond patterns of the new compounds as well as the phosphoric triamides found in the Cambridge Structural Database (CSD). The analysis of hydrogen bond patterns updates the previous work (Toghraee, Pourayoubi and Divjakovic in Polyhedron, 2011, 30, 1680) on phosphoric triamides with a C(O)NHP(O)[N]2 skeleton, and extends the analysis to other phosphoric triamides i.e. ones without a CO attached to the N of N–PO. For the new phosphoric triamides we also investigated their spectroscopic features (31P, 1H, 13C, and 15N NMR, mass spectroscopy, IR spectroscopy), measured the 1J(15N,31P) coupling constants and discussed the effective parameters.
我们介绍了七种新的磷酸三酰胺的合成和表征,随后分析了新化合物以及剑桥结构数据库(CSD)中发现的磷酸三酰胺的氢键模式。对氢键模式的分析更新了之前关于具有 C(O)NHP(O)[N]2 骨架的磷酸三酰胺的研究成果(Toghraee、Pourayoubi 和 Divjakovic,发表于《多面体》(Polyhedron),2011 年,30 期,1680 页),并将分析扩展到其他磷酸三酰胺,即 N-PO 的 N 端没有连接 CO 的磷酸三酰胺。对于新的磷酸三酰胺,我们还研究了它们的光谱特征(31P、1H、13C 和 15N NMR、质谱、红外光谱),测量了 1J(15N,31P) 耦合常数,并讨论了有效参数。
