The successive scale-up of electrochemical reactions is crucial with regard to the implementation of technical electro-organic syntheses. Therefore, we developed a scalable modular parallel-plate electrochemical flow cell. One distinctive feature of this flow cell is that the temperature of the electrodes can be easily controlled from the back side via an external cooling circuit, enabling high reproducibility of electrochemical conversions. Because the gap between the electrodes is kept narrow, small amounts or no supporting electrolyte is required. The practicability and performance of the novel flow cell were validated by three different anodic phenol–phenol cross-couplings as test reactions.

大型，高度模块化的窄间隙电解流动池及其在苯酚的脱氢交叉偶联中的应用

电化学反应的连续放大对于实现技术有机电合成至关重要。因此，我们开发了可扩展的模块化平行板电化学流通池。该流通池的一个显着特征是可以通过外部冷却回路轻松地从背面控制电极的温度，从而实现电化学转化的高重复性。因为电极之间的间隙保持狭窄，所以需要少量或不需要支持电解质。新型流动池的实用性和性能通过三种不同的阳极苯酚-苯酚交叉偶联作为测试反应进行了验证。
