Abstract

Hydrogen transfer from artepillin C to cumylperoxyl radical was followed. It was found that artepillin C exhibits an efficient radical-scavenging activity against cumylperoxyl radical in an aprotic medium. The absence of an effect of Sc³⁺ on the k_HT values demonstrated that the hydrogen transfer from artepillin C to cumylperoxyl radical proceeds via one-step hydrogen atom transfer.
