Substituent Effects on Redox Potentials of Novel Amphoteric Teerphenoquinone Analogues. Unsymmetricaly Substituted 2,5-Bis(4-oxo-2,5-cyclohexadien-1-ylidene)-2,5-dihydrothiophenes

Article abstract of DOI:10.1246/cl.1993.157

The unsymmetrically substituted derivatives of the title heterocycle-extended quinone have been synthesized and the substituents effects on their electrochemical properties have been investigated.The first reduction potentials and the first oxidation pote
