Full TextAbstract
Abstract. Two new phosphoramidates with formula RC(O)NHP(O)[NH(tert-C4H9)]2, RC6H5, (1) and CCl3, (2) were synthesized and characterized by IR, 1H-, 13C-, 31P NMR, mass spectroscopy and elemental analysis. The structures confirmed by X-ray single crystal determination. Compound 1 appears as two conformers (1a and 1b) in solid state as well as solution. Both compounds (1 and 2) exist in the polymeric chains in crystalline lattice produced by hydrogen bonding that for compound 1, there are two independent infinite chains; each of them composed of one of the two conformers. Inhaltsübersicht. Zwei neue Phosphoramidate der Formel RC(O)NHP(O)[NH(tert-C4H9)]2 mit R C6H5 (1) und CCl3 (2) wurden synthetisiert und durch IR-, 1H-, 13C-, 31P-NMR- und Massenspektroskopie sowie durch Elementaranalysen charakterisiert. Ihre Strukturen wurden durch Einkristall-Röntgen-Diffrakto-metrie ermittelt. Verbindung 1 bildet zwei Conformere (1a und 1b) sowohl im festen Zustand wie in Lösung. Beide Verbindung (1 und 2) bilden als Folge von Wasserstoffbrückenbindungen polymere Ketten. 1 bildet zwei unabhängige unendliche Ketten der beiden Conformere.
