Abstract: The rates of hydrolysis of three phosphonamides, N, N- dimethylphenylphosphonamide (XII), N-(phenylphosphony1) pyrrolidine (XIII), and N- (phenylphosphony1) morpholine (XIV), have been investigated. There is first-order dependence on acidity in the pH range 4-7 with a pH independent region at low pHs, consistent with saturation due to complete formation of the neutral amide. The specific rate ...
