Kinetics of hydrolysis of diisopropylaminofluorophosphate (MIPAFOX) has been studied using copper(II) diamine complexes as catalyst. The pseudo-first order rate constants, activation energies and ∆S^⧧ have been calculated. The high negative ∆S^⧧ suggests complex formation between Cu^ll complex and the substrate in the transition state.
