Stability and Reactivity of Tocopherols: Theoretical Study

In the search for the tocopherols structure-reactivity relationship, our calculations showed that the GAP, which is the difference between the energy values of the frontier orbitals, decreases during the passage gas/aqueous medium for the isoforms α, β and γ. But it increases for isoform δ. This mea...

Description
Summary:In the search for the tocopherols structure-reactivity relationship, our calculations showed that the GAP, which is the difference between the energy values of the frontier orbitals, decreases during the passage gas/aqueous medium for the isoforms α, β and γ. But it increases for isoform δ. This means that the latter is less reactive and less soft than the others in aqueous medium. On the other hand, the chemical descriptors calculations revealed that the transfer of electrons takes place in the direction α < β < γ < δ in the gas state and aqueous medium.
