Synthesis of 1,4-Benzoquinone Derivatives Having Two Side-Armed Polyethers and Crown Ethers, and Their Electrochemical Study in the Presence of Alkali Metal Cations (Na+ and K+)

Article abstract of DOI:10.1246/bcsj.61.3026

Several crown ethers and two side-armed polyethers which have reducible quinonoid groups were prepared.Some of them, 7a, 7b, and 7d, showed highly enhanced cation-binding properties for the Na⁺ cation upon electrochemical reduction.
