Hydroxy‐ ( 1a‐3a ) and hydroxyalkyl‐substituted benzoquinones ( 6a‐8a, 27a ), suited to be immobilized by esterification with polyacrylic acid, are prepared. Their cathodic reduction potential E p,c (1) correlates linearly with their substituent constant. The cathodic reduction of dioxygen and the palladium(II)‐catalyzed anodic oxidation of alkenes are mediated by the benzoquinones 7b, 8b and 27b , respectively.
