The phenolic OH bond dissociation enthalpy (BDE) represents reaction enthalpy of the HAT mechanism.
Obtained results indicate that electronwithdrawing substituents increase the bond dissociation enthalpy (BDE) andionization potential (IP), while electrondonating ones cause a rise in the proton affinity (PA).
We refined existing theoretical methods so we could accurately predict the chemical behaviour of antioxidants, based on the bond dissociation enthalpy (BDE) of the weakest, and hence most reactive, bond in each molecule (1).
