Electrode dissolution was monitored in real-time during Kolbeelectrolysis along with the characteristic products. The fastdetermination of appropriate reaction conditions in electroorganicchemistry enables the minimization of electrodedegradation while keeping an eye on the optimal formationrate and distribution of products. Herein, essential parametersinfluencing the dissolution of the electrode material platinum ina Kolbe electrolysis were pinpointed. The formation of reactionproducts and soluble platinum species were monitored duringpotentiodynamic and potentiostatic experiments using anelectroanalytical flow cell coupled to two different massspectrometers. The approach opens new vistas in the field ofelectro-organic chemistry because it enables precise and quickquantification of dissolved metals during electrosynthesis, alsoinvolving electrode materials other than platinum. Furthermore,it draws attention to the vital topic of electrode stability inelectro-organic synthesis, which becomes increasingly importantfor the implementation of green chemical processesutilizing renewable energy. |
