Phosphoric bis-(o-Methoxyphenyl amide) chloride, a C-N-P containing ester, on kinetic examination exhibited a rate maximum (via the Neutral form only) at 4.0 M-HCl and gave second-order kinetic rate coefficients during hydrolysis in the acid range, 0.01-7.0M HCl at 40( 0.5)0C. In the low acid range Zwitterionic species while in the higher acid range the undissociated form have been assessed as the major contributory reactive forms, undergoing bimolecular (Arrhenius Parameters) hydrolysis with P-N bond fission, The synthesis of the bis-amide was possible by the phosphorylation procedure and identification of the product was achieved by elemental analysis, and 31P NMR study in particular.
