One-Electron Transfer in Electrochemical Oxidation of Calix[4]resorcinolarenes and Their Aminomethylated Derivatives

Calix[4]resorcinolarenes in the presence of amine and aminomethylated calix[5]resorcinolarenes in DMF undergo similar multistage electrochemical oxidation. The first stage proceeds at low potentials and involves reversible one-electron transfer with formation of stable phenoxy radicals.
