Methanethiyl radicals (CH3S^.) are shown to react with cyclic ethers containing double bonds to give addition and hydrogen abstraction from the allylic positions.The esr spectra of the corresponding radicals have been determined.In some cases radicals arising from rearrangement (probably 1,4 H-shift) were obserwed. t-Butoxyl radicals also give abstraction and addition with the same substrates.In two cases the barriers to ring inversion for six-membered ring radicals have been determined.
