The kinetics of the reduction of methyl viologen and 9,10-anthraquinone-2-sulfonate by the benzopinacol anion

The reduction of methyl viologen (MV2+) and 9,10‐anthraquinone‐2‐sulfonate (AQS) by the benzopinacol anion in 50% (v/v) propan‐2‐ol/water was investigated spectroscopically. The rate constants for these reactions were found to be 12.9 ± 0.2 and 0.23 ± 0.01 M−1 s−1, respectively. © John Wiley & Sons, Inc. Copyright © 1992 John Wiley & Sons, Inc.
