Non-covalent π–π stacking interactions turn off non-adiabatic effects in proton-coupled electron transfer reactions

Abstract

π–π stacking interactions do not necessarily change the mechanism involved in the H transfer reaction between phenol and phenoxyl radicals. We propose that, in such cases, the e⁻ is transferred between the π delocalized moieties, while the H⁺ is transferred between the donor and acceptor atoms.
