摘要 : Several new carbacyiamidophosphates with formula (X)C(O)NHP(O)(NC6H12)2, X = CH2Cl, 1b; CHCl2, 2b; CCl3, 3b; CF3, 4b; MeC6H4, 5b; BrC6H4, 7b; ClC6H4, 8b were synthesized and characterized by ~1H, ~(31)P and ~(13)C NMR and IR spect... 展开 Several new carbacyiamidophosphates with formula (X)C(O)NHP(O)(NC6H12)2, X = CH2Cl, 1b; CHCl2, 2b; CCl3, 3b; CF3, 4b; MeC6H4, 5b; BrC6H4, 7b; ClC6H4, 8b were synthesized and characterized by ~1H, ~(31)P and ~(13)C NMR and IR spectroscopy and elemental analysis. The effect of PNCC dihedral angles on the ~3J(P,C aliphatic) was studied. The structures of the 4b, 7b and 8b were determined by single-crystal X-ray diffraction techniques. The structural data of these compounds are compared with similar carbacyiamidophosphates. 收起
