The electrochemistry of m-terphenylthio-, seleno-, and telluroethers was studied
using cyclic voltammetry in acetonitrile. All of the compounds studied showed irreversible
oxidations. The first oxidation potentials for the thio- and selenoethers are less positive than
expected. This facilitation in oxidation is ascribed to through-space S···π and Se···π interaction,
respectively, on removal of an electron. No evidence for a comparable effect was
found for the phenyltelluro-ethers studied.
