Abstract

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 1H, 13C, 31P 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.
