Electrosynthetic reactions are performed in either custom‐made reactors that are developed and machined in‐house or commercially available systems that offer good reproducibility but come at a high cost. To bridge this divide between customizability and reproducibility, we have developed the Open‐ESyn, which is a suite of 3D‐printed components compatible with the popular ElectraSyn. This collection of parts increases the electrosynthesis that can be performed with the ElectraSyn, expanding, for example, the scale, temperature and the type of electrodes that can be used. The standardized reactor environment can be inexpensively recreated, thereby maintaining the reproducibility of the ElectraSyn ecosystem. [ABSTRACT FROM AUTHOR]

Electrochemical fluorination reactions of organic compounds frequently employ hydrogen fluoride reagents that are corrosive. The corrosive nature of these reagents necessitates either the construction or purchase of cells that are stable to hydrogen fluoride, which require high‐cost materials, machining time and expertise. Herein, we offer an alternative solution using 3D printing, which is an inexpensive and rapid manufacturing technique. We have designed, printed and shared four different cell types in polypropylene and tested them in an electrochemical alkene difluorination reaction in the presence of triethylamine ⋅ 3HF and pyridinium poly ⋅ (HF).

The choice of electrode material is critical for achieving optimal yields and selectivity in synthetic organic electrochemistry. The material imparts significant influence on the kinetics and thermodynamics of electron transfer, and frequently defines the success or failure of a transformation. Electrode processes are complex and so the choice of a material is often empirical and the underlying mechanisms and rationale for success are unknown. In this review, we aim to highlight recent instances of electrode choice where rationale is offered, which should aid future reaction development. [ABSTRACT FROM AUTHOR]
