New phosphoric triamides (R1P(O)Cl2, 1; R1P(O)(OH)2, 2; R1P(O)(NHCH2CH=CH2)2, 3; R1P(O)[NHCH(CH3)2]2, 4; R1P(O)[NH-C(CH3)3]2, 5; R1P(O)(NHCH2-C4H3O)2, 6; R1P(O)(NHCH2C6H5)2, 7; R1P(O)[N(CH3)(CH2C6H5)]2, 8; R1P(O)[NHCH(CH3)(C6H5)]2, 9; R1 = 2,4-Cl2-C6H3C(O)NH) were synthesized by the reaction of N-2,4-dichlorobenzoyl phosphoramidic dichloride with various cyclic aliphatic amines and the products were characterized by 1H, 13C, 31P NMR, IR spectroscopy and elemental anal. Surprisingly, the 1H NMR spectrum of 2 indicated long range 6J (P, H) coupling constant = 1.3, 1.4 Hz and those of mols. 3, 4, 6–8 display long-range 4J (H, H) coupling constants (1.8-1.9 Hz) for the coupling of aromatic protons in 2,4-dichlorophenyl rings. 1H NMR spectra indicated 3J (PNCH) for enantiotopic and diastereotopic benzylic CH2 protons in compounds 7 and 8. The spectroscopic data of newly synthesized compounds were compared with those related N-benzoyl derivatives The structures of compounds 5, 8 and 10 (2,4-Cl2-C6H3C(O)NHP(O)[N(CH2CH(CH3)2)2]2) have been determined by x-ray crystallog. The structures form centrosym. dimers through intermol. strong -P=O…H-N-hydrogen bonds. The dimers connect to each other via rather strong and weak C-H…O plus weak C-H…Cl H-bonds to produce a 1-D network for 5 while 3-D polymeric chains for 8 and 10.
