Full TextAbstract
A new phosphoric triamide compound with formula 3,5-F2C6H3C(O)N(H)P(O)X2, X2= NH-CH2-C(CH3)2-CH2-NH (1) was synthesized and characterized by 1H, 13C, 19F, 31P{1H} NMR, IR spectroscopy, CHN elemental analysis and X-ray crystallography. This is the first example of an aliphatic diazaphosphorinane in which the oxygen atoms of phosphoryl and carbonyl groups are located in anti positions toeach other. Compound 1 forms a 1D ladder chain from centrosymmetric dimmers that are produced by intermolecular P=O…H-N hydrogen bonds. The 1H NMR and 13C NMR spectra show 3J(H,F) and 1-3J(C,F). The 13C NMR spectrum of compound 1, containing sixmembered ring diamine group, shows that 3J(P,Caliphatic) >2J(P,Caliphatic).
