Alkyl radicals having (t-butylthio)carbonyl group on β- or γ-position gave β- or γ-thiolactones whereas the homologous radical did not give δ-thiolactone. These reactions involve intramolecular radical substitution on the sulfur atom of thioester group. Ethylthioesters have much less reactivity to the same substitution.
