While many steps in an oxidative cyclization reaction can be important, it is the cyclization step itself that plays the central role. If this step does not proceed well, then optimization of the rest of the sequence is futile. We report here that the key to the cyclization is channeling the reaction down the correct […]

Electroorganic Synthesis and the Construction of Addressable Molecular Surfaces
In this Minireview, an electroorganic synthesis approach to the construction of addressable, complex molecular surfaces is described along with the parameters that guided the development of that synthetic approach. The result of the work is a synthetic toolbox that will allow microelectrode arrays to be used for the “real‐time” monitoring of small molecule interactions with […]
Paired Electrochemical Reactions and the On‐Site Generation of a Chemical Reagent
While the majority of reported paired electrochemical reactions involve carefully matched cathodic and anodic reactions, the precise matching of half reactions in an electrolysis cell is not generally necessary. During a constant current electrolysis almost any oxidation and reduction reaction can be paired, and in the presented work we capitalize on this observation by examining […]
Organic Electrochemistry and a Role Reversal: Using Synthesis To Optimize Electrochemical Methods
Diblock copolymers are excellent coatings for microelectrode arrays because they provide a stable surface that can support both synthetic and analytical electrochemistry. However, the surfaces that are optimal for synthetic studies are not the same as the surfaces that are optimal for analytical studies. Hence, no one surface provides an ideal platform for both building […]

Using Physical Organic Chemistry To Shape the Course of Electrochemical Reactions
While organic electrochemistry can look quite different to a chemist not familiar with the technique, the reactions are at their core organic reactions. As such, they are developed and optimized using the same physical organic chemistry principles employed during the development of any other organic reaction. Certainly, the electron transfer that triggers the reactions can […]
Anodic Cyclization Reactions and the Mechanistic Strategies That Enable Optimization
Oxidation reactions are powerful tools for synthesis because they allow us to reverse the polarity of electron-rich functional groups, generate highly reactive intermediates, and increase the functionality of molecules. For this reason, oxidation reactions have been and continue to be the subject of intense study. Central to these efforts is the development of mechanism-based strategies […]
Insights into the Mechanism of Anodic N-N Bond Formation by Dehydrogenative Coupling
The electrochem. synthesis of pyrazolidine-3,5-diones and benzoxazoles by N-N bond formation and C,O linkage, resp., represents an easy access to medicinally relevant structures. Electrochem. as a key technol. ensures a safe and sustainable approach. We gained insights in the mechanism of these reactions by combining cyclovoltammetric and synthetic studies. The electron-transfer behavior of anilides and […]
Electrochemical synthesis of benzoxazoles from anilides – a new approach to employ amidyl radical intermediates
A novel electrochemical method for the synthesis of benzoxazoles from readily available anilides is reported. Various functionalities are tolerated and good yields can be achieved. By employing common electrode materials and a simple constant current protocol, this method is an attractive new alternative to conventional pathways. Tile Gieshoff, Anton Kehl, Dieter Schollmeyer, Kevin D. Moeller […]
Paired Electrolysis in the Simultaneous Production of Synthetic Intermediates and Substrates
In electrochem. processes, an oxidn. half-reaction is always paired with a redn. half-reaction. Although systems for reactions such as the redn. of CO2 can be coupled to H2O oxidn. to produce O2 at the anode, large-scale O2 prodn. is of limited value. One may replace a low-value half-reaction with a compatible half-reaction that can produce […]
