Synthesis, structural and spectroscopic characterization of thiophosphorodiamidates and effect of ZnCl2 on the hydrolysis of the P–N bond
摘要:
New N,N'-dibenzylthiophosphorodiamidate derivatives were synthesized from the corresponding thiophosphorodichloridate intermediates and benzylamine. Several compounds with formula 2-MeC6H4OP(S)(NHBn)(2) (6), 2-FC6H4OP(S)(NHBn)(2) (7), 2-ClC6H4OP(S)(NHBn)(2) (8), 4-MeC6H4OP(S)(NHBn)(2) (9) and 4-t-BuC6H4OP(S)(NHBn)(2) (10) were synthesized and characterized by H-1, C-13, P-31 NMR, IR, mass spectroscopy and elemental analysis. The single crystal X-ray diffraction studies of 6 and 7 have been described. ZnCl2 assisted P-N bond hydrolysis of thiophosphorodiamidates was investigated. (C) 2012 Elsevier Ltd. All rights reserved.
