Na+-Catalyzed Reduction of Semiquinone Radical Anions by NADH Analogues

Article abstract of DOI:10.1246/cl.1992.1497

Stable radical anions such as p-chloranil radical anion (Cl4Q^-.) are reduced by NADH analogues, 1-benzyl-1,4-dihydronicotinamide (BNAH) and 10-methyl-9,10-dihydroacridine (AcrH2), to yield the corresponding hydroquinone anions.The addition of NaClO4 to the BNAH-Cl4Q^-. system results in a significant increase in the rate of the one-electron reduction of Cl4Q^-., while no acceleration effect has been observed by the addition of Bu4NClO4.
