Conclusions

  1. 1.

    A study has been made of the kinetics of benzene oxidation to diphenyl by palladium perchlorate in aqueous solutions containing up to 90% AcOH at 60–90°C.

  2. 2.

    This reaction was first order with respect to both Pd(II) and benzene. The variation of the reaction rate with the acetic and hydrochloric acid concentrations was such as to indicate the necessity of having both electrophilic [Pd(II) ions] and nucleophilic [acetate ions] particles present in the system.

  3. 3.

    The most probable reaction mechanism was one involvingσ bonding of palladium to phenyl with proton transfer from benzene to the acetate ion in the limiting step transition state.
